Abstract

A novel sensorless controller for induction motor is presented. Indirect field oriented control approach and Lyapunov-adaptive design are exploited for the derivation of the controller and the speed-flux observer constituting the proposed solution. No direct integration of the neutrally stable stator flux dynamics is adopted. Persistency of excitation conditions with clear practical interpretation is derived to guarantee local exponential stability with a defined region of attraction for the proposed approach. Simulation results are provided.
