The single- neuron controller is introduced, which is designed based on supervisory hebb learning algorithm with combination of practical control experience. The meanings and dereferencing principle of each parameters in the single-neuron controller are analyzed and the single-neuron controller is emulated by using Matlab software under the circumstance of giving a step-input signal with the simulation contents of the connection weights, the influence of k value＇s variation on the system and its choosing method, and the comparison of their anti-jamming capabilities and regulating performances between the single-neuron PID controller and the conventional PID controller as well. The simulation result proves that the single-neuron PID controller has good parameter self-setting capability; better capacity of resisting disturbance and little overshoot, its control effect is superior to the conventional PID controller in all directions. The single-neuron PID controller .used for resistance furnace temperature control system can achieve better control effect than the traditional PID controller.
