Abstract—This paper reviews the model of the induction motor in stationary reference frame, with stator current and rotor flux components as state variables. The state feedback linearizing and decoupling control as applied to the induction motor drive is presented. With this control, the drive system is decoupled into two linear subsystems: electrical and mechanical. Comprehensive and systematic procedures are developed to determine the gains of the Proportional–Integral (P-I) controllers for electrical and mechanical subsystems. The controlled drive system is simulated in MATLAB SIMULINK and experimented in RTDS environment, and results are presented. 
