Abstract
Based on the position adjustment of CRTS Ⅱ type orbital plate in the height direction,a set of electro-hydraulic proportional position control system is designed to solve the problems of time-consuming and low degree of automation of manual regulator.The principles of control system and the stability of the adjustment is introduced, the systematical mathematical modeling is established and the stability and steady-state error of the closed-loop system is analyzed, then PID regulator is utilized to check the calibration of the system,as well as Ziegler-Nichols method is utilized to calculate the parameters of PID.Finally, an investigation into the dynamic simulation of the system via Simulink toolbox is made.According to the analysis of simulation results, it is proved that the set of electro-hydraulic proportional position control system with regulator is feasible, and its precision, stability and responsiveness are able to meet the needs of actual construction.关键词
