A control method of induction motor fed by current regulator pulse width modulation inverter is presented to obtain fast dynamic response. This proposed method is based on the closed-loop control of the torque angle and has the merits of being simple in implementation and insensitive to rotor resistance variation. The proposed scheme utilizes the inverter frequency as the necessary system stabilizing, while the current amplitude merely adjusts the motor steady state flux level. The stabilization is achieved by regulating the phase angle between stator current and rotor flux. The design of proposed scheme is introduced. Speed controller using synchronous reference frame PI regulator is employed as an outer loop. Moreover, another synchronous reference frame PI regulator is employed as inner loop to control the tangent of torque angle. An analytical method for obtaining the rotor speed based on model reference adaptive system without using stator and rotor resistance is proposed. By using this method, speed sensor-less closed-loop torque angle control with no influence of the stator and rotor resistance variations obtained. Also, this proposed method does not require any integrators in its algorithm. In this paper, the control scheme was successfdly implemented and tested in laboratory using a high-speed signal processor (DSP). The experimental results validate the theoretical predictions with different dynamic operating conditions.
