Robust servomechanism with preview action for polytopic uncertain systems
This paper considers the robust servomechanism design for a polytopic uncertain system subject to a previewable reference signal. Based on the robust mixed LQ/H= criterion, we develop a design method of a state feedback controller with integral and preview actions achieving the robust tracking performance in terms of linear matrix inequalities. A numerical example is also included to show the a...
متن کاملSliding Mode Proximate Time-optimal Servomechanism
A discrete-time sliding mode proximate time-optimal servomechanism is developed using nonlinear sliding mode tangent to a reference velocity profile. Instead of a strong nonlinear function causing control chattering in discrete-time, a linear control is designed around the sliding surface. The resulting servomechanism delivers a bounded motion about the sliding surface even in the presence of p...
متن کاملDiscrete-time optimal preview control
The field of Preview Control is concerned with using advanced knowledge of disturbances or references in order to improve tracking quality or disturbance rejection. Areas of application include guidance of autonomous vehicles, robotics and process control. This thesis studies Optimal Discrete-Time Preview Control, in which the controlled plant is assumed to be unconstrained, linear and discrete...
متن کاملAsymptotic Characteristics of Optimal Preview Control System
One of the useful method to improve a designed control system performance is utilization of the future desired signal and/or disturbance signal, if possible. Until now, optimal preview control system and preview pre-compensator are considered on the basis of optimal regulator theory and model matching approach. Effectiveness of the preview control system is shown in the application to servo sys...
