CCR（constant current regulator） is a constant value, time-varying control system. The characteristics of the controlled object （CCR） were analyzed, and the factor and characteristics of the design controller were discussed. The defects of the traditional PID and the partition set control parameters in the controlled object were analyzed, the principle of neuron PID controller and its concrete structure was given, the neuron PID algorithm was improved, which could online correct neuron PID coefficient, and overcome shortcomings of traditional PID. The control performance of the controller is superior,real-time, and complies with international and national technical parameters.
