并联机床伺服系统双自适应模糊滑模控制
Double Adaptive Fuzzy Sliding Mode Control for Hydraulic Servo System of Parallel Machine
摘要
Abstract
Taking a single-channel control of parallel machine tools as the research object, an double adaptive fuzzy sliding mode control method adapted to the asymmetric cylinder hydraulic servo system controlled by symmetric valve was presented to make the output of the system follow the reference signal progressively, so that the problems of dynamic performance asymmetry, low accuracy, low stability were resolved. Double adaptive fuzzy sliding mode control was more suited to complex systems with higher order nonlinearity and strong interference. The simulation results demonstrated that the double adaptive fuzzy sliding mode control system could greatly improve the dynamic performance and control precision of parallel machine tools. The steady-state error is only 20% of PID controller.关键词
