| Abstract: | A pneumatic load simulator,loaded with a cylinder controlled by proportional valve,was established.Its characteristics and control strategy were studied.The model of the simulator was built and a fuzzy-PID controller with feed forward was designed and simulated by Matlab.Using real-time control program,the experiments of 0.5,1,2 and 5 Hz triangle wave stimulation were carried out.The experimental results show that the performance of the pneumatic load-simulator is better at low frequency. |
