Study on the simulation and application of hydraulic servo system of crankshaft straightening machine based on immune neural network PID control algorithm

The principle of immune feedback and immune-neural network PID algorithm are respectively introduced in this paper. An immune-neural network PID controller is designed by which an adaline neural network is selected as antibody inhibition and adjustment function and the parameters of immune-neural network PID controller are determined by simulation. The transfer function of hydraulic servo system of crankshaft straightening were introduced in different working conditions. The immune-neural network PID controller was applied to hydraulic servo system of crankshaft straightening. The results of simulation and equipment operation shows that it has better control effect and can meet the needs of the hydraulic servo system of crankshaft straightening machine.
