Real time implementation of backstepping-multiscalar control to induction motor fed by voltage source inverter

A novel version of nonlinear induction motors (IM) control algorithm based on the backstepping approach has been proposed in this work. For that, the conventional mathematical model of IM is replaced by the multiscalar one, which is more suitable for application of the backstepping design. By using such combination, the system has fast dynamic response, better load disturbance rejection capability, less parameters sensitivity and better tracking performance of rotor speed and rotor flux magnitude. The effectiveness of the proposed control structure is validated by simulation as well by experiment under critical disturbance conditions.     

Advanced Backstepping controller for induction generator using multi-scalar machine model for wind power purposes

This paper presents a new non-linear control Algorithm based on the Backstepping approach for an isolated induction generator (IG) driven by a wind turbine. For this purpose and in order to reduce the complexity of the real induction machine mathematical model, the multi-scalar machine model is exploited. The machine delivers an active power to the load via a converter connected to a single capacitor on the dc-side. So, during the voltage build-up process, the necessary stator currents references to be injected by the converter are calculated from the desired active power to be sent to the load and the rotor flux magnitude. Simulation results show that the proposed control provides perfect tracking performances of the DC-bus voltage and the rotor flux magnitude to their reference trajectories.
