Nonlinear control of induction motor depends on nonlinear changes of state variables. The use of this method provides a novel model of induction motor. As a result, the drive system is fully decoupled and two separate mechanical and electromagnetic subsystems can be obtained. The aim of this work is to develop nonlinear control methods using multiscalar model of induction motor MM. Voltage source inverter feeds the used model of induction motor with hysteresis current controllers. The input commands to hysteresis algorithm is the amplitude and angular frequency of stator current. The proposed control system with additional feedback has been simulated in real time. For this aim a digital control system based on a digital signal processor with a fixed point arithmetic is presented (TMS320C25/50).
