Fast Terminal Sliding Mode Control of Permanent Magnet In-Wheel Motor Based on a Fuzzy Controller

Abstract

A fast terminal sliding mode control is proposed in this paper for improving the dynamic performance and robustness of a permanent magnet in-wheel motor system driven by a voltage source inverter. Firstly, a fast terminal sliding mode approaching law was designed to accelerate the approaching rate of the control system. Then, a torque load observer was designed to compensate for disturbances and uncertainties. Finally, fuzzy rules were designed to suppress the chattering phenomenon. Simulation and experimental results demonstrated that the fast terminal sliding mode control strategy presented better response speed than the conventional sliding mode control strategy. It had better dynamic performance and anti-interference and effectively reduced the chattering phenomenon in the control process.

An Electronic Line-Shafting Control Strategy Based on Sliding Mode Observer for Distributed Driving Electric Vehicles

“…Park built the EV mathematical model and simulate the special conditions for the driving and steering of the vehicle [14]. Huang and Tu proposed a fast terminal sliding mode algorithm for control of the in-wheel motor of DDEV, this control scheme is not sensitive to the change of internal parameters of the motor and can effectively improve the control precision of the single motor [15]. Zhang adopted a sliding-mode observer to adjust the parameters variation and efficiently reduce the disturbances caused by the internal parameter fluctuation of motor [16], [17] presented a nonlinear optimal finite-time tracking controller based on a state-dependent Riccati equation for the Multi-Motor driving system, which adopted nonlinear sliding mode controller to overcome the approaching problem of conventional SMC.…”

A novel hierarchical nonlinear proportional-integral fast terminal sliding mode control for PMSM drives

“…A fast terminal sliding mode (FTSM) control strategy was first proposed by Yu and Man 22 Because of its superior performance, the FTSM control strategy has been widely used in permanent magnet in-wheel motor, 23 nonlinear uncertain mass-spring system, 24 gantry cranes, 25 second-order underactuated systems, 26 and so on. In the conventional approach, the hierarchical SM control strategy was motivated to eliminate the chattering of the conventional SM control strategy.…”
