Dynamic Performance Improvement Of Induction Motor Using Radr Controller

P Raja, SK Meera shareef


The primary concern of researchers is the control of induction motor. Proportional-integral- derivative (PID) control and direct torque control (DTC) have been proposed for induction motors [1-6]. Due to the following issues control of induction motor is challenging: 1) the dynamic system of an induction motor is highly nonlinear; 2) the rotor resistance varies because of heating. In this paper, RADR control with reduced order extended state observer (RESO) is applied for induction motor control. For controlling a slip ring induction motor the RADAR control is employed. All the three phases are assumed to be identical and symmetrically located with respect to each other. In this paper Induction Motor Model Responses with RADR and DTC control are compared in  MATLAB/SIMULINK .
