【 摘 要 】

Aiming at the problem that the variable frequency hydraulic system of a filling machine is high in nonlinearity and weak in stiffness, and the response speed of ordinary PID control is slow, the fuzzy adaptive control strategy is adopted to improve the system performance. Based on the joint simulation of AMESim and Matlab, the expert experience and the PID controller are combined by designing the fuzzy adjuster, so that the controller can automatically adjust the parameters according to the changes of the system working conditions, so as to improve the dynamic characteristics of the system.
