A nonlinear tracking control for sensorless induction motors
We propose a novel tracking control for induction motors in which only stator currents are used for feedback. Local exponential lotor speed and flux modulus tracking are achieved for any constant reference value and for restricted time-varying reference signals; any known motor parameters values (including constant load torque) and any initial condition, including rotor speed and fluxes, belonging to an explicitly computed domain of attraction are allowed.
