Application of LMI-based Method in Motive Simulation Table Servo System

摘要

A LMI-based method was employed during the mixed sensitivity design of a certain kind of motive simulation table servo system to analyze some well-developed methods used for the mixed sensitivity design, and further investigate the actual characteristics of the table servo system. The simulation results show that the adopted method not only removed structural constraints prescribed in the standard H_∞ control theory and overcomes some computational weaknesses in some of the nonstandard H_∞ control theory, but also solves some practical issues in the mixed sensitivity design of the table servo system.
