【Abstract】 Anodic oxidation power supply system was a complex non-linear and time-varying system, and it was difficult to establish a mathematical model. The traditional PID control method can not ensure that the anodic oxidation power supply current has the characteristics of constant current, strong anti-interference ability and small overshoot. In order to solve these problems, an algorithm for control of anodic oxidation power supply current based on RBF neural network PID was developed. RBF neural network has strong self-learning ability, which can adjust the parameters of traditional PID controller adaptively. The simulation results showed that the control algorithm based on RBF neural network PID has fast response speed, small overshoot and anti-interference ability.更多还原
