Robust chattering-free (higher order) sliding mode control for a vector-controlled induction machine

Goh, Keng; Dunnigan, Matthew; Williams, Barry

Abstract

The chattering behaviour that is inherent in standard sliding mode control is often an obstacle for practical application if neglected. In this paper, special attention is given to a particular chattering-free control method: 2-sliding “super twisting” control algorithm. Several
control algorithms, including the standard and chatteringfree control algorithms, are assessed via position and speed control of a vector-controlled induction machine. Attention has also been paid to the friction dynamics in the induction machine system. Linear and non-linear friction dynamics in the induction machine model are considered. Simulation results using an induction machine model are first reported, followed by implementation results. A pre-defined reference signal is employed for tracking capability assessment as well as robustness against a high inertia load (about double the
machine inertia) and DC motor load.
