Hydraulic Servo System

Material experiment system of hydraulic servo system is subject to load disturbance and load disturbance is a function of standard mechanical parameters of rock samples. Rock mass is very discrete, anisotropy, composition is not single and inelastic[. Traditional tester can't get the complete stress-strain curve of rock[ material, in order to solve the shortage of the traditional hydraulic servo system, in this paper, the fuzzy PID control is successfully applied to the hydraulic servo system, through the experiments and get good effect.

Engine Mount

A MRF fluid engine mount with controlled annular access, inertia track and decoupler is designed. Through the experiment it can be seen that the low frequency performance of the mount is greatly improved. Then the dynamic low frequency performance of the mount using the fuzzy PID control method of two degrees-of-freedom system in different engine speed is simulated and the results show that the fuzzy PID control method is effective to reduce the body acceleration.

Traditional PID control has not been able to meet the control requirements. This paper has designed one type of Fuzzy PID controller to use in NC Machine Servo System. Simulate the response of Fuzzy PID controller and traditional PID controller by Simulink in MATLAB. The simulation results indicated that the Fuzzy PID controller had quick response speed, strong robustness, high precision and non-overshoot etc. It improved the whole control performance of NC Machine Servo System.
