Self Tuning Proportional Integral Control System using Neural Network

摘要

The present invention relates to a speed control system of an electric motor that uses the STPI controller, PI controller and neural network (NN ), a parallel connection is made to the command speed for the electric motor () and the actual speed () receiving the error of speed control of the motor a torque command current component necessary to () STPI controller and outputting a The actual speed from the motor () speed meter that measures the The torque current component command () and the flux component current command () and the rotor position of the motor () accepts input phase voltage command value (a img id = "8" file = "112005044024407-pat00008.jpg "wi =" 27 "he =" 6 "img-format =" jpg "/) of the current controller output, the phase voltage command value () receives the space for driving the motor and a PWM inverter vector. Therefore, the electric motor, so the system can respond appropriately to the non-linear characteristics, the system changes such as parameter variations can maintain the robustness and high performance.
