This paper presents a novel stator flux oriented induction motor control scheme. It utilises a sliding-mode controller in the stator flux control loop. The existence condition of sliding mode control is derived, and chattering suppression at steady-state is also considered. A proportional controller is used in the torque control loop to simplify the control scheme without compromising performance. Design formulas are given for the controller parameters. They are not based on the mathematical motor model but only need rated parameters. Experimental results are shown to prove the effectiveness of the control strategy in transient and steady state operations.
