Many satellites require the use of slewing solar panels. A laboratory model of a slewing frame is presented here as an article for testing control laws for such solar arrays. A slewing frame presents a challenging control problem because the primary action of slewing induces torsional vibration which is relatively uncontrollable with respect to the slewing actuator. An experimental investigation ...

This paper deals with stability and stabilization of a deployable flexible beam. It is proved that the motion of the structure is basically stable in the station-keeping phase and deploying phase, but unstable in the retracting phase, if there is no control for it. Boundary controllers are proposed for the structure, which may dissipate the unwanted vibration and rotation energy of the structure, thus stabilize the structure during all the motion phases.
Many satellites require the use of slewing solar panels. A laboratory model of a slewing frame is presented here as an article for testing control laws for such solar arrays. A slewing frame presents a challenging control problem because the primary action of slewing induces torsional vibration which is relatively uncontrollable with respect to the slewing actuator. An experimental investigation of controlling this structure for combined slewing and vibration suppression is presented. The frame is modeled using finite element methods verified by experimental modal analysis. Analytical results indicate that the torsional motion can be suppressed by including an active strut in the feedback loop. Non-colocated and colocated control laws are implemented using the active strut as a sensor and an actuator. The relative effectiveness of each design in suppressing the torsional motion is discussed.
A simple model and a hybrid position/force controller of constrained flexible manipulators having a heavy end-effector are presented by introducing a set of equivalent springs which represent all the flexibilities of a constrained manipulator. The dynamic relation of joint angles, vibration of the end- effector, and constraint force are derived on the basis of the proposed model. For measuring the vibrations and the contact force, accelerometers and a force sensor are used. Output signals of the sensors are fed back to the driving motors for controlling the position of the end-effector and the contact force. A feedback controller incorporating an observer is presented on the basis of the dynamic model. Simulation results are shown.<<ETX>>
This paper describes a shaking vibration suppression approach for electric vehicles, which provides quick and smooth acceleration response. The vehicle that is driven by an electric motor can provide a quick acceleration response that depends on the characteristics of the motor's torque response. However, at the same time, the fast acceleration rate of the motor torque causes an uncomfortable shaking vibration that originates from the twisting torque of the drive shaft. To achieve a balance between the vehicle accelerating performance and the comfortable ride, a new shaking vibration control method is proposed. The proposed control system is composed of a feed-forward compensator with an inverse filter and a feedback compensator by applying a perfect zeroing method. The feed-forward filter can suppress a shaking vibration induced by motor output torque, and the feedback compensator suppresses a shaking vibration caused by a disturbance input such as a model error or a disturbance torque input. Driving tests were conducted with an experimental fuel cell vehicle operated by an electric motor control. According to the driving test results, it has been confirmed that quick acceleration response was obtained without any shaking vibration, and the usefulness of the proposed control approach is confirmed
Internet congestion algorithm decides the queue sizes and quality of service (QoS) of network. Based on the mechanism of Internet congestion control, a new active queue management (AQM) algorithm based on the fuzzy logical controller (FLC) is presented. When the system states are far off the equilibrium, a sliding-mode controller (SMC) is applied to control the states returning the neighbor of the equilibrium in a limit time. For decreasing the vibration of SMC, a state feedback controller (SFC) is gradually used to replace SMC in a small region of the origin. A fuzzy logical controller (FLC) is introduced to realize the switch between SMC and SFC. Finally, simulations show the validity of the new AQM algorithm
A generalized Forecasting Compensatory Control (GFCC) strategy is developed using the receding forecasting horizon approach and a simplified i-step ahead forecasting model. The characteristics and robustness of this GFCC algorithm are presented and analyzed. This algorithm has been successfully applied to the vibration control of an experimental beam subjected to impulse as well as random excitations. Both simulation and experimental results show the new GFCC strategy very effective.
A two-level control scheme is presented for lightweight, flexible robot arms; the first based on rigid body motion and the other for suppressing structural vibrations. The gross motion is controlled through a combined feedforward and feedback action. The compensator for elastic vibrations is designed using the concept of intelligent structures. The algorithm is based on independent modal space control (IMSC) leading to the design of decoupled modal controllers from which actual compensating inputs are synthesized. The procedure is illustrated by a two-link flexible manipulator. Simulation results show the effectiveness of the proposed approach and its scope for an interactive evaluation of system performance.<<ETX>>
This paper presents an approach to integrate structure and control design. The objective of the problem is to find: (i) the optimal values of the structure parameters, e.g. stiffness, damping ratios, and actuator location parameters, etc.; (ii) an optimal stabilizing state feedback controller such that the active control energy is minimized subject to: (a) the prespecified RMS constraints on the outputs, and (b) the constraints on structure parameters. The algorithm is given in terms of LMIs, and the convergence is guaranteed. The solution is optimal in the "local sense". An example is given to illustrate the effectiveness of the algorithm.
The Advanced Space Structures Technology Research Experiments (ASTREX) is a precision structure situated at the Phillips Laboratory, Edwards Air Force Base, CA. The structure is a test bed to develop, test and validate control strategies for large-angle, three-axis slewing maneuvers and vibration suppression. The ASTREX facility consists of the test article (with primary, secondary and tertiary substructures along with mirrors). Rational fractional approach is used to obtain coprime equations in a multivariate setting. Parameterized compensators are obtained for regulation and stabilization. Simulation results are presented to show the accomplishment of vibration suppression.<<ETX>>
An active vibration control structure applying a filter-x recursive least- squares adaptive algorithm was developed for suppressing gearbox vibration effectively and fast. The system employs a piezoelectric stack actuator to deliver the active control force through a rolling element-bearing. In order to evaluate the feasibility of the system, an integrated simulation system employing a controller based on filter-x recursive least-squares algorithm was created. A virtual prototype of a two-stage gearbox was integrated into the simulation system. The results yield 9-14dB accentuation in the gearbox vibration levels at the frequency with highest power. Additionally, the proposed control system exhibits faster convergence rate under various working conditions. Joint simulation demonstrate that the proposed FxRLS system exhibits faster convergance rate under various working conditions, up to 14dB reduction in the vibration response at frequency with highest power can be achieved.
