The research of closed Loop Control of AC motor based on J-M transformation control

Two classical strategies, vector control and direct torque control, are applied to control AC motor. The performance of motor has made a great qualitative leap. In this paper, a novel control modal strategy, J-M transformation control, is presented. The closed loop control method based on the navel modal is to research the robust performance of J-M transformation control. Initially brief introduction of the fundamental formulas of J-M transformation strategy is presented. The control block diagram of closed loop control unneeded parameters of AC motor based on J-M transformation control is analyzed in detail. Subsequently, Simulation results show that the method of closed loop control based on J-M transformation control is effective to control AC motor.
