A Takagi-Sugeno fuzzy control of induction motor drive: experimental results

Abstract

This paper studies an observer-based H ∞ tracking control problem for induction motor in order to guarantee the field-oriented control (FOC) performances. Firstly, the physical model of the induction motor is approximated by the T-S fuzzy technique in the synchronous d-q frame rotating. Then, a fuzzy observer-based feedback control is synthesised to guarantee the control performances. The proposed controller is based on a T-S reference model in which a desired trajectory has been specified. The performances of the trajectory tracking are analysed using the Lyapunov theory and the L 2 optimisation. The gains of the observer and the controller are obtained by solving a set of LMIs constraint in a single step. To highlight the effectiveness of the proposed strategy experimental results are presented for a 1.5 KW induction motor.
