Abstract: This paper presents hardware implementation of anti-windup proportional integral (AWPI) controller-based scalar control of three phase induction motor (IM) drive using digital signal processer (DSP). The space vector pulse width modulation (SVPWM) is used generally for motor control application. The proposed control scheme is built on DSP which reduces speed error by using AWPI controller. The response of AWPI controller is used to modify amplitude and speed reference of rotating vector in stationary plane. The controller performance is assessed by MATLAB/Simulink simulation results and validated by experimental results using TMS320F28335 DelfinoTM kit. A comparative assessment is also presented between conventional PI controller and proposed controller. The proposed AWPI controller gives the better performance in terms of peak overshoot and settling time during transient conditions.

Keywords: scalar control; digital signal processor; anti-windup PI controller; V/f control.
