Jerk Limited Time Optimal Control of Flexible Structures
This paper addresses the problem of designing jerk limited timeoptimal control profiles for rest-to-rest maneuvers of flexible structures. The variation of the structure of the jerk profile as a function of the permissible jerk is studied. An optimal control problem is formulated which includes constraints to cancel the poles corresponding to the rigid body and flexible modes of the system and ...
متن کاملMinimax Robust Jerk Limited Control of Flexible Structures
This paper is concerned with the design of robust jerk limited controllers for flexible structures. In order to eliminate residual vibration at the end of the maneuver, a time-delay filter, forming the command input, is used. A minimax optimization scheme is employed to make the controller more robust with respect to parametric uncertainties. The degree of robustness can be chosen arbitrarily. ...
متن کاملDesensitized Jerk Limited-Time Optimal Control of Multi-Input Systems
The problem of designing jerk limited-time optimal control pro les for rest-to-rest maneuvers of exible structures with multiple actuators is addressed. The problem formulation includes constraints to cancel the poles corresponding to the rigid-body mode and exible modes of the system and to satisfy the boundary conditions of the rest-to-rest maneuver. Further constraints can be added to i...
متن کاملRobust Time-Optimal Control of Flexible Structures With Parametric Uncertainty
The design of robust time-optimal controllers using the sensitivity concept is presented in this paper. A parameter optimization problem is solved using the Switch Time Optimization algorithm to determine a bang-bang control profile that minimizes the maneuver time subject to the constraint that the sensitivity of the final states with respect to system parameters are zero. The proposed approac...
متن کاملOptimal Near-Minimum-Time Control Design for Flexible Structures
Amethod for generating a near-minimum-time control input for exible structures is presentedwith the objective of minimizing the maneuver time and the residual energy of the exible modes. The method is based on smoothing the bang–bang, time-optimal control input designed for the rigid-body mode. Smoothing is accomplished through the addition, to the basic time-optimal control problem for the...
