RISE-backstepping-based robust control design for induction motor drives

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.

Real-time nonlinear speed control of an induction motor based on a new advanced integral backstepping approach

“…Lately, the Backstepping approach has been widely used in case of nonlinear systems control (Ben Regaya et al, 2018; Krstic et al, 1995; Mehazzem et al, 2017a; Rkhissi et al, 2017). It is a powerful tool in facing structural uncertainties and external disturbances, which are an obstacle for control designing and implementation for real systems.…”

“…Adaptive algorithms are included in the Backstepping structure to get better results (Ben Regaya et al, 2018; Dezhi et al, 2019; Lin et al, 2008). In Rkhissi et al (2017), a new IM control law is developed using the Backstepping design associated with the robust integral sign of the error (RISE) technique, which is used to compensate the load torque disturbance under specific conditions. We can find in literature other approaches that combine Backstepping with other nonlinear techniques such as fuzzy logic and sliding mode control (Aichi et al, 2018a).…”

An adaptive PI control design for multi-phase machines in healthy and faulty operations

“…However, if optimal H ∞ controller solution is obtained, real-time implementation of such controllers may be problematic. For improving dynamic motion control performance of induction motor drives, a model-based back-stepping control algorithm in the FOC scheme was proposed in Ameid et al (2017) and Rkhissi-Kammoun et al (2017). However, this method requires identifying a precise system model.…”
