轧机液压伺服系统滑模变结构控制
Sliding Mode Variable Structure Control of Hydraulic Servo Systems
摘要
Abstract
Considering the problem that the surface of the steel plate is not smooth and nonlinear characteristicssuch as the viscous friction and the uncertainty of system parameters so on, the nonlinear model of hydraulic servo system of the rolling mill was researched and the sliding mode variable structure controller was designed and the value range of the parameter K in the sliding mode to ensure the stability of the system was analyzed.According to the results of the simulation, the sliding mode variable structure controller designed could effectively overcome the nonlinear friction of the system and solve such problem as potholes on steel plate and so on, and has better robustness to the uncertainty of system parameters.By the contrast simulation with the fuzzy PID control, the response speed, steady state error and anti-interference performance are all better.关键词
