Abstract

Purpose

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.

Design/methodology/approach

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.

Findings

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.

Originality/value

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.

Abstract

Purpose

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

Design/methodology/approach

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

Findings

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

Originality/value

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