Resumen: Fuzzy-logic based controllers have been recently proposed to implement vector control methods in induction motors. This paper presents a new switching self-tuning type of fuzzy controller aimed at obtaining a satisfactory performance (rise time and overshoot) in the motor response. Two fuzzy controllers, a PI-like fuzzy controller and a PD-like fuzzy controller are applied in different regions of the control space. Their responses are combined by another fuzzy inference machine which divides the control surface in a fuzzy way. Also a simple adaptive fuzzy system have been used to tune the proposed controller to provide a simple way to redefine the controller and obtain a better control action. Simulation results show that this scheme has the ability to improve the transient and steady state performance of the controlled system from the simple PD-like and PI-like fuzy controllers. The scheme has been implemented using a DSP and the simulation results have been experimentally validated
