In order to study the performance of valve-controlled motor's speed governing system,we first introduce the AMESim and Simulink co-simulation technology,and then establish the accurate system model by AMESim software's PID controller,to solve the difficult problem in the adjustment of conventional PID parameter with the application of neural network control theory and then use the improved algorithms of single neuron PID controller,. Finally we build the simulation model of control system based on S-Functio...
