Abstract
In this chapter, three control strategies for the induction motor (IM) are studied, thanks to their robustness properties, their implementation simplicity, and their time computation cost. To compare the performance of the control strategies, specific trajectories have been defined by a so-called control benchmark (see Sect. 1.6 in Chap. 1). For the control design, it is assumed that all the variables are measurable and all parameters are known (or known except bounded uncertainties). Firstly, a classical field-oriented control [7] is introduced. Next, a robust backstepping controller is designed. However, the robustness of the classical backstepping controller is improved, thanks to integral terms that are added at each step of the iterative procedure. Finally, another robust control design for the IM is introduced, based on sliding mode control techniques. For the classical sliding mode control design, the chattering effect phenomenon is a drawback that involves a limited implementation of such a controller. Thus, to reduce the effects of this phenomenon, a high-order sliding mode controller (HOSM) is designed to track the desired rotor speed and the modulus flux references.

The interest of a such feedback, which has been detailed in [13], is that it allows to minimize gain values of the control discontinuous function.
