✦ Synopsis

A new design strategy is proposed for the development of full-order indirect "eld-oriented induction motor controller. The proposed output feedback controller permits to achieve global exponential asymptotic speed and #ux tracking in presence of unknown load torque. In addition, it ensures asymptotic decoupling of the speed and #ux subsystems, asymptotic linearization of the speed subsystem and improved robustness with respect to rotor resistance variation, providing improved energy e$ciency. The limited implementation complexity, joined to a simple procedure for performance speci"cation and controller parameters' tuning, makes the proposed controller suitable for industrial application. Simulation results are presented, con"rming excellent tracking quality and robustness. The proposed non-linear controller and the adopted design procedure are suitable for both further theoretical development (robust and adaptive control) and industrial applications where high dynamic performance is required.
