H∞ Control for Striped Steel Centering of Electro-hydraulic Servo Control System
It is the control problems of hydraulic servo system that parameter perturbation and the uncertainty caused by external interference difficult to solve. Based on robust control,we can still ensure good quickness and steady state performance even when the system is under ultimate conditions through designing a controller with steady structure and constant parameters. This paper focuses on applying robust control 亣 H to realizing the electro-hydraulic servo control. In connection with the production line of cold rolled sheet of some steelworks electro-hydraulic servo control system for striped steel centering, we designed a 亣 H robust controller with optimal mixed sensitivity on the basis of mixed sensitivity design method. The relative simulation results show that the controller we designed ensures that the robust stability of the closed-loop system and good follow performances, at the same time, it restrains the model perturbation and external disturbance to the influence of the system, which settled the system of anti-disturbance and model disturbance well.
