Abstract :
The control system of pressure testing machine is uncertainty, nonlinear and it is vulnerable to the impact of load change. In this paper, a new variable universe fuzzy PID control algorithm is introduced to solve the problem of the fuzzy controlling dead zone and the adjustment of PID control algorithm, which is based on the perfect theory of PID controller. Compared with the traditional control algorithms, the simulation results of the test-bed, which is based on MATLAB /Simulink 6.0 show that the new control algorithms has strong adaptability and improve the control precision and the dynamic performance.
