Abstract: Induction motor constitutes an established test bed in the automatic control theory frame-structure as it is a higher order, multiple input-output, nonlinear system operating under uncertainty conditions. The sliding mode control (SMC) method is a well-developed, promising control procedure appropriate for nonlinear, time-dependent, uncertain systems. Due to its dynamic nature and robustness towards uncertainties, SMC is a most suggested technique for implementing in induction motor drives. This paper focuses on implementing various continuous-time, SMC strategies characterised by the reaching law approach in an induction motor drive. The paper also proposes a comparative analysis of various continuous-time reaching-laws on the performance of the motor towards parameter and load variations and the chattering issues.

Keywords: sliding mode control; SMC; reaching law; constant reaching law; proportional reaching law; power reaching law; exponential reaching law; enhanced exponential reaching law; vector control; motor drives.
