Simulation analysis of electro hydraulic proportional position system based onthe speed of feedback and PID
摘要
Abstract
Based on the mathematical model of the electro-hydraulic proportional position system, a simulation model of electro-hydraulic proportional position system was built by using the Simulink tool in Matlab software, and the dynamic analysis was carried out.According to the actual production requirements, Bode chart was drawn to verify the stability of the system.Using of speed feedback and PID control, the dynamic characteristics of the position system were optimized and designed.The simulation results show that the overshoot of the position system decrease 54.5%, and the response time is reduced by 0.62 s, the steady state error is reduced by 0.01m through adjusting of combine velocity feedback and PID.After the system was adjusted, its impact was dissipation, the response speed was more stable and fast, the control precision was higher, which provides the basis for the deep level optimization of the system.关键词
