Nonlinear Integral Backstepping Control for Induction Motor drive with Adaptive Speed Observer using Super Twisting Strategy

Abstract : This paper presents a nonlinear Integral backstepping control approach applied to an induction motor fed by a power voltage source without speed sensor. We present the implementation of the integral backstepping control for induction motor drives based on the field oriented control technique. We also present the mechanism of adaptive super twisting speed and rotor flux observers with the only assumption that from stator voltages and currents are measurable. The objective is to improve the speed control, the rotor flux control under load torque disturbances and parameter variations. The overall stability is demonstrated using Lyapunov theory. Simulation results prove clearly high robustness against disturbances; the estimated flux and rotor speed converge to their actual values.
