Abstract :
The response of an induction motor following a supply or load change consists typically of two stages, namely an initial acceleration stage and a final steady state stage. Based on this observation, this paper presents a two-stage speed control method which involves the control of current and frequency. The controller is easy to implement and is insensitive to motor parameter changes. Satisfactory performance has been obtained from a simulation study on a 7.5 kW motor
