Abstract

In order to realize precise control to the device of hydraulic excavator,by analyzing the structure and character of electronic-hydraulic proportion model,the mathematic model is deducted,and the time domain and the frequency domain character of the system are analyzed.Because the speed of system response is very slow,after adjusting the control system-gain,PID method is selected to control the model,and the parameter is fixed on by trial confirming method,then the improvement of system's performance is analyzed;to prove the correctness of the arithmetic and the precision of the parameter,result is showed by experiment of trajectory control of excavator,this theory research is also proved to be meaningful.
