Abstract :
The nonlinear control especially the feedback linearization is widely used in the induction motor control and PWM converters nowadays. The feedback linearization control performance can be improved by solving the problems caused by the sampling and calculating time of digital processor. The proposed new feedback linearization in this paper is by employing the state observer and predictive controller. Simulation and experimental results validate the analytical predictions.
