Induction Motor (IM) can be found in many industrial applications such as precision machining and automation processes, especially robotics.  In this paper, firstly, we investigate the problem of nonlinear discrete-time flatness-based controller design for IM.  Secondly, we propose a new control strategy named cascaded flatness-based control (CFBC) by considering the nonlinear characteristics of IM in order to eliminate the static errors of state variables.  Simulation is shown to demonstrate the benefits of the proposed CFBC and the performance evaluation is given by experimental results.

Keywords: flatness-based control, induction motor, nonlinear system, real-time control
