Trajectory

View this topic in
A trajectory is the path that a moving object follows through space as a function of time. The object might be a projectile or a satellite, for example. It thus includes the meaning of orbit—the path of a planet, an asteroid or a comet as it travels around a central mass. (Wikipedia.org)

  • Full-State Regulation Control of Asymmetric Underactuated Surface Vehicles

    In this paper, a challenging problem of full-state regulation control (FSRC) for an asymmetric underactuated surface vehicle (AUSV) suffering from disturbances is solved. The FSRC objective is divided into 2 sub-tasks, i.e., reaching trajectory (RT) guidance and tracking controller synthesis with underactuation and disturbances. The RT guidance is achieved by devising a circular orbit (CO) accurately passing through the desired full-state waypoint (FWP). Using a series of coordinate transformations, tracking error dynamics are shaped in a translation-rotation cascade form with respect to the CO- center frame. Using finite-time approach, lumped disturbances are accurately estimated by exact observers which facilitate synthesizing surge and yaw controllers. By creating a new coordinate, translation subsystem is converted to a lower-triangular form. Combining with backstepping technique, cascade analysis and Lypunov approach, translation and rotation controllers are derived systematically, and render the entire closed-loop FSRC system globally asymptotically stable. Hence, the AUSV is regulated to the desired FWP. Simulation studies on a benchmark AUSV are conducted to demonstrate remarkable performance.

  • Yaw-Guided Trajectory Tracking Control of an Asymmetric Underactuated Surface Vehicle

    In this paper, suffering from both complex uncertainties and underactuations,$accurate$trajectory tracking control problem of an asymmetric underactuated surface vehicle (AUSV) is first addressed by guiding yaw dynamics which are$free of persistent excitation (PE)$. Using nested coordinate transformations, the AUSV is formulated in a cascade structure consisting of translation and rotation subsystems with complex uncertainties. Finite-time uncertainty observers (FUOs) are devised to exactly estimate transformed uncertainties, and enable$separation principle$in controller and observer syntheses. By virtue of creating yaw-guided dynamics, rotation tracking is shaped to stabilize yaw and sway tracking discrepancies, simultaneously, in collaboration with yaw controller. Nominal dynamics of translation tracking errors are globally asymptotically stabilized by surge control synthesis using cascade analysis and Lyapunov approach, and thereby contributing to global asymptotic stability of the entire translation-rotation tracking system. Eventually, an FUO-based yaw-guided tracking control (FUO- YTC) scheme of an AUSV with complex uncertainties is established. Simulation studies demonstrate remarkable performance.

  • Laguerre based model predictive control for trajectory tracking of nonholonomic mobile robots

    This paper presents a Laguerre parametrization approach to employ Model Predictive Control (MPC) for the trajectory tracking problem of a non- holonomic mobile robot with input and state constraints. A time-varying error model is obtained for the trajectory tracking of the mobile robot. Then, a Laguerre based MPC (LMPC) for time-varying systems is designed and tuned to ensure asymptotic stability of the system. The proposed algorithm considers input and states, including velocity and acceleration, constraints to provide stability. It is shown that the proposed method is able to reduce the computation times. In order to confirm the effectiveness of the proposed method, extensive simulations results are provided.

  • Experimental validation of a car-like automated guided vehicle with trajectory tracking, obstacle avoidance, and target approach

    The proposed hierarchical sliding mode control (HSMC) for the car-like automated guided vehicle (CLAGV) includes two parts: one is virtual control input (VCI), the other is sliding mode tracking control (SMTC) [1]. Moreover, a single software/hardware based platform develops the software for the control, image processing and trajectory planning algorithms, and the hardware for the control signal (e.g., the PWM for driving the motor) and for the sensor inputs (e.g., the decoder for obtaining the position or velocity of motor, the USB interface for capturing the image). The RGB-D vision system can detect the obstacle(s) through the depth image and recognize the specific object through the SURF (Speed-Up Robust Feature) method. The estimated distance with respect to the vehicle can execute the task of obstacle avoidance (OA) and target approach (TA). Finally, the experiments of the straight-line and circular trajectory tracking with the simultaneous OA and TA of the vehicle confirm the effectiveness, efficiency, and robustness of the proposed system.

  • Motion control of a tractor with multiple trailers

    This paper presents the design and motion control of a practical system where a car-like robotically steerable tractor tows multiple four-wheeled passive trailers. This specific system is rarely dealt with in academic studies but is very commonly applied in real-world industrial applications. The objective is to achieve the trajectory tracking control of the whole system with minimized tracking deviation happening to each trailer. This has long been challenging because of the high degree of non-holonomy caused by the increasing number of linked trailers. This paper simplifies the control problem by considering the whole tractor-trailer system as the iterative linkage of just two types of connection mechanism between axles - the off-hooked connection and the trailer's steering mechanism. In both connection mechanisms, it is designed to make the rear vehicle stably and precisely follows its front vehicle. Since the motion of a passive vehicle is only affected by its preceding vehicle, once the tractor at the very front is controlled to track the reference trajectory, the trajectory tracking control of the whole system can be achieved by iteratively applying the inner tracking property of the two connection mechanisms. The numerical simulation result is also presented to verify the control scheme.

  • Investigating Functional Redundancies in the Context of Vehicle Automation – A Trajectory Tracking Perspective

    Level 3+ automated driving implies highest safety demands for the entire vehicle automation functionality. For the part of trajectory tracking, functional redundancies among all available actuators provide an opportunity to reduce safety requirements for single actuators. Yet, the exploitation of functional redundancies must be well argued if employed in a safety concept as physical limits can be reached. In this paper, we want to examine from a trajectory tracking perspective whether such a concept can be used. For this, we present a model predictive fault-tolerant trajectory tracking approach for over-actuated vehicles featuring wheel individual all-wheel drive, brakes, and steering. Applying this approach exemplarily demonstrates for a selected reference trajectory that degradations such as missing or undesired wheel torques as well as reduced steering dynamics can be compensated. Degradations at the physical actuator limits lead to significant deviations from the reference trajectory while small constant steering angles are partially critical.

  • Visually servoed trajectory tracking of quadrotors with the kinematic model

    The visually servoed trajectory tracking of quadrotors has attracted many academic researchers over the past decade, and numerous controllers are proposed for this challenging problem. The trajectory tracking controller proposed in this paper follows the Position Based Visual Servoing (PBVS) paradigm. Most of the PBVS controllers, if not all, are implemented assuming that the position of the quadrotor has been accurately recovered with an independent estimator. Therefore the rigorous trajectory tracking stability cannot be promised due to the separation principle does not hold for the general nonlinear systems. Accordingly, a new PBVS controller is proposed in this paper for the trajectory tracking of quadrotors by embedding a novel adaptive estimator into this new controller to estimate the position of the quadrotor online. It is proved by Lyapunov theory that the proposed adaptive PBVS controller gives rise to the asymptotic trajectory tracking and the convergence of the estimated position to the actual one. An experiment is conducted to validate the effectiveness of the proposed controller.

  • On the Trajectory Tracking Problem of Underactuated Deep Diving AUV

    The large dive depth of underactuated AUV leads to the complicated external interference in the dive process, which greatly affects the performance of AUV dive motion control. In order to solve the problem of external interference, this paper first divides the external interferences into the constant current interferences and the buoyancy interferences that vary with the depth changes. Then the mathematical model is built and the adaptive rate is designed for the external interference. Secondly, the AUV dynamic model under external interference is established and the three-dimensional trajectory tracking is implemented by the backstepping control method which defines the virtual velocity error variables. The control method can ensure that the AUV can dive to a designated area when there is external interference and can also solve the singular value problem in the traditional backstepping method. Finally, the system stability is proved by Lyapunov function. The simulation results show the effectiveness of the proposed method, which achieve the purpose of controlling the deep-depth spiral dive of the AUV.
