Research of Induction Motor Mathematical Frequency Speed Regulation
This design which is based on the theorem of three-phase induction motor mathematical model, builds the three-phase induction motor model through the MATLAB / Simulink, uses the PWM pulse generator to control the inverter thyristors conduction in order to establish a different from the traditional open-loop speed control system of current or the speed double-loop frequency control system, and makes the closed system obtain a better control performance of speed by having changes of the parameters.
