Experimental evaluation of induction motor robust control using sliding mode linearization technique

Abstract

This paper, deals with a new input-output sliding mode linearization control for induction motor combined with field oriented control (FOC). To control the speed and rotor flux modulus, we develop two loops. The first one, inner loop, allows to linearize the system by a choose of closed loop poles to achieve a good linearization. The choice of a particular sliding surface permits to create a link between sliding mode theory and input-output linearization. The second one, external loop, allows to modify the dynamics obtained by the first one using PI controller to guarantee stability and tracking performance of speed and rotor flux modulus. The effectiveness of this new approach has been successfully verified through experimental results.
