ABSTRACT. In this paper, algorithm for direct speed and flux control of induction motors using online estimation of the rotor resistance and load torque is described and validated with experimental results. This method is based on the variable structure theories and is potentially useful for adjusting online the induction motor controller unknown parameters (load torque and rotor resistance). The nonlinear compensator presented provides voltage inputs on the basis of rotor speed and stator currents measurements and generates estimates for both the unknown parameters and the non-measurable state variables (rotor flux and derivatives for the stator current and ...
