Fifth International Conference on Advanced Robotics 'Robots in Unstructured Environments, 1991
Based on the kinematic studies of motion for a vehicle equipped with a pair of motorized wheels which, by having appropriate velocities, can provide traction forces as well as steering action, a steering control strategy is derived. The angular velocities for the right and left wheels are considered, the two control inputs which cause a system to follow a desired ...

In this paper, we consider the fifth order discrete model of an aircraft (longitudinal) control system which possesses three slow (velocity, pitch angle and altitude) and two fast (angle of attack and pitch angular velocity) modes and exhibits a two-time scale property. Using the recent results of the time scale analysis of discrete control systems, the high-order discrete model is ...

Previous work on stabilization of compressor surge is extended to include control of the angular velocity of the compressor. A low-order centrifugal compressor model is presented, where the states are mass flow, pressure rise, and rotational speed of the spool. Energy transfer considerations are used to develop a compressor characteristic. In order to stabilize equilibria to the left of the ...

This is an addendum to the control design solutions presented by Jankovic et al. (1996) for the benchmark TORA system. A high-pass filter is proposed to approximately differentiate the input position signal, thereby yielding an approximate velocity signal for use in the input control. The filter and control input are designed through a Lyapunov analysis, thus accounting for the effect ...

Based on the kinematic studies of motion for a vehicle equipped with a pair of motorized wheels which, by having appropriate velocities, can provide traction forces as well as steering action, a steering control strategy is derived. The angular velocities for the right and left wheels are considered, the two control inputs which cause a system to follow a desired trajectory. Assuming these inputs to be linear functions of the two errors associated with path tracking problem (position and orientation errors), through an appropriate Lyapunov function, a control policy is determined. The path tracking behaviour of a mobile robot using such a control law is demonstrated by computer simulation.<<ETX>>
In this paper, we consider the fifth order discrete model of an aircraft (longitudinal) control system which possesses three slow (velocity, pitch angle and altitude) and two fast (angle of attack and pitch angular velocity) modes and exhibits a two-time scale property. Using the recent results of the time scale analysis of discrete control systems, the high-order discrete model is decoupled into low-order slow and fast subsystems. The results of the decoupled system are found to be in excellent agreement with those of the original system.
Previous work on stabilization of compressor surge is extended to include control of the angular velocity of the compressor. A low-order centrifugal compressor model is presented, where the states are mass flow, pressure rise, and rotational speed of the spool. Energy transfer considerations are used to develop a compressor characteristic. In order to stabilize equilibria to the left of the surge line, a close coupled valve is used in series with the compressor. Controllers for the valve pressure drop and spool speed are derived. Semiglobal exponential stability is proved using a Lyapunov argument.
This is an addendum to the control design solutions presented by Jankovic et al. (1996) for the benchmark TORA system. A high-pass filter is proposed to approximately differentiate the input position signal, thereby yielding an approximate velocity signal for use in the input control. The filter and control input are designed through a Lyapunov analysis, thus accounting for the effect of the pseudo-velocity signal in the closed-loop system (in spite of the fact that the filter output is not guaranteed to fully recreate the true velocity). The stability analysis shows that the closed-loop system is globally asymptotically stable. Computer simulations illustrate that the transient behavior of the controllers designed here is nearly equivalent to those proposed by Jankovic et al.
To establish empirical verification of a stabilizing controller for nonholonomic systems, the authors implement a hybrid control concept on a 2-DOF mobile robot. Practical issues of velocity control are also addressed through a velocity controller which transforms the mobile robot to a new system with linear and angular velocity inputs. Experiments in the physical meaning of different controller components provide insights which result in significant improvements in controller performance.<<ETX>>
A general tracking control problem with saturation constraint for nonholonomic mobile robots is proposed and solved using the backstepping technique. A global result is given in which some artificial assumptions about the linear and the angular velocities of mobile robots from recent literature are dropped. The proposed controller can simultaneously solve both the tracking problem and the regulation problem of mobile robots. With the proposed control laws, mobile robots can now globally follow any path such as a straight line, a circle and the path approaching to the origin using a single controller. Computer simulations are presented which confirm the effectiveness of the tracking control laws. Moreover, practical experimental results concerning the tracking control are reported with saturation constraint for mobile robots.
Because of the transport of strain across rollers in a tension control system, the output from one tension control station is a disturbance to the next station. Tension disturbances are also transmitted upstream if frictional engagement between the web and the roller is inadequate or if velocity control of a driven roller between the spans is imperfect. Differential equations for process tension control are derived, simplified, and linearized. Tension control by means of torque control as well as velocity control of a roller or rewinding roll of material is examined, and the two methods are compared.
In this paper we make the important observation that the attitude and angular velocity control systems for gas-jet aircraft and underwater vehicles are of a special form: they are affine control systems with constant control distributions and multi-affine drifts. For this general class of systems, we can construct (and check the existence of) bounded controls driving the system from initial to final regions of the state space. This can be used for tasks requiring repositioning or changing the velocity of the vehicle under constraints on both controls and state. We illustrate the procedure by solving the problem of changing the angular velocity of a parallelepiped aircraft under velocity and control constraints imposed by the task. The method should be seen as a "maneuver" procedure, allowing automatic generation of control laws for bringing the system in a desired region of its state space. If stabilization to a point is required, then locally stabilizing control laws can be used after the maneuver.
