Description
Summary:This paper presents an efficient implementation scheme for the closed-loop speed control of an induction motor with constant V/f, slip regulation and incorporating dasiaspace vector pulse width modulationpsila (SVPWM). The system is an embedded system which incorporates an 8-bit reduced instruction set computer (MCU) to implement the speed control and the modulation scheme. Scalar control is inferior to the modern field oriented control in terms of efficiency and response time but it requires considerably lesser hardware resources. Use of space vector modulation as the modulation technique gives a better harmonic response and higher efficiency as compared to the normal regular sampled pulse width modulation techniques. The drive incorporates optimized algorithms and low cost hardware to provide a better cost-performance relationship. The system also includes features for the digital over-current protection and soft-starting of the motor.
