Abstract

We propose a nonlinear adaptive speed and torque controller of induction motors with unknown rotor resistance. All the system parameters except rotor resistance are assumed to be known and only the stator currents and rotor speed are assumed to be available. The desired speed and torque should be any continuously differentiable bounded function. A complete proof of the global stability without singularity is given and the output error will converge to zero asymptotically. Finally, simulation and experimental results are given to demonstrate the effectiveness
