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 کاملRobust Dynamic Stiffness Design of a Linear Servo System
As a popular controller used in the industrial servo drives, the pseudo derivative feedback with feedforward (PDFF) scheme has 3 parameters for tuning to achieve a good trade-off design between tracking and dynamic stiffness. However, the two parameters in the feedback path of the PDFF controller are restricted to constant for design simplicity that limits its dynamic stiffness. This paper pres...
متن کاملRobust Qft-based Position Control of Electrohydraulic Servo System
This paper presents the design of a robust controller using the Quantitative Feedback Theory technique for an asymmetric hydraulic cylinder electro-hydraulic servo system based upon a linear, parametrically uncertain model in which some of the uncertainties reflect the variation of the parameters, and taking the external disturbance into account. After the derivation of a realistic nonlinear di...
متن کاملRobust Controller Design Using Edge Theorem for Modular Servo System
The paper deals with the design of robust controllers for uncertain SISO systems in the frequency domain. The approach is accomplished with the Edge Theorem and the Neymark D-partition method for the affine model. The proposed method guarantees the required degree of stability. The practical application is illustrated by the robust controller design for a Modular Servo System.
متن کاملH∞ filtering for a system with uncertain preview information
An H∞ filtering problem for a system driven by uncertain previewable signals is discussed, and a design method of an H∞ filtering law is presented. The problem pertains to generalized H∞ filtering with previewable reference signals or disturbances. The solvability condition is characterized by the solutions of differential/algebraic Riccati equations, and some interpretations are provided for t...
