This paper aims to address the speed and flux tracking problem of an induction motor (IM) drive that propels an electric vehicle (EV). A new continuous control law is developed for an IM drive by using the backstepping design associated with the Robust Integral Sign of the Error (RISE) technique.

First, the rotor field-oriented IM dynamic model is derived. Then, a RISE-backstepping approach is proposed to compensate for the load torque disturbance under the assumptions that the disturbances are C² class functions with bounded time derivatives.

The numerical validation results have presented good control performances in terms of speed and flux reference tracking. It is also robust against load disturbances rejection and IM parameters variation compared to the conventional Field-Oriented Control design. Besides, the asymptotic stability and the boundedness of the closed-loop signals is guaranteed in the context of Lyapunov.

A very relevant strategy based on a conjunction of the backstepping design with the RISE technique is proposed for an IM drive. The approach remains simple and can be scaled to different applications.

This work focuses on modelling, robust controller design and real time control of 3-DOF Helicopter.

This study presents an improved H∞ controller for this aerial vehicle

Simulation and experiment results are addressed to demonstrate the capability of this proposed control strategy to counteract the effect of this disturbance

In order to reduce the complexity of the standard H∞ structure, a fixed order control design is proposed as original approach
