“…However, PMLSM is easily affected by uncertainties such as parameter variations and external disturbances owing to the lack of transmission mechanisms (Wang et al, 2018, Rahman et al, 2015. Therefore, to achieve high performance of the system, effective control methods should be adopted to reduce the impact of these uncertainties (Hu et al, 2023).…”

Aiming at the uncertainties existing in the permanent magnet linear servo system, an intelligent second-order sliding mode control (ISOSMC) method is proposed to achieve high precision and strong robustness. First, the dynamic model of PMLSM with uncertainties is established. To conquer the uncertainties, a second-order sliding mode control (SOSMC) method based on the PID sliding surface is designed. Additionally, to further reduce chattering caused by sign function, a sinusoidal saturation function is applied in the control law of SOSMC. Due to the value of the uncertainties is di cult to obtain, a recurrent radial basis function neural network (RBFNN) uncertainty estimator is introduced to estimate the uncertainties and a robust compensator (RC) is developed to reduce the approximation error of recurrent RBFNN. To guarantee the performance of the ISOSMC system, Lyapunov function is employed to prove the stability. Experimental results demonstrate ISOSMC possesses favorable tracking performance and strong robustness against the parameter variations and load disturbances.

“…With the increasing awareness of environmental protection and energy conservation, pure electric vehicles have developed quickly due to their noteworthy energy-saving and environment benefits [1][2][3]. In order to meet the various driving conditions of electric vehicles, the permanent magnet synchronous motor (PMSM) using high-performance rare earth permanent magnet (PM) materials have been widely applied to the power source of electric vehicles, which demonstrating high power density and high efficiency [4][5][6][7][8][9]. However, as non renewable strategic resource, rare earth materials are affected by upstream raw materials, patent barriers and price fluctuations, which reduced the large-scale commercial application of PMSM [10].…”

The novel rare earth variable flux permanent magnet synchronous motor (PMSM) for electric vehicles is proposed. The structure and magnetic field regulation characteristics are analyzed, the variation of magnetic density, no-load back electromagnetic force and output torque with speed was studied through finite element simulation. The weak magnetic field expansion speed performance of the novel PMSM has been verified through experimental equipment. The adjustable electromagnetic field with running speed on the rare earth PMSM increases the high-speed operation range of vehicle.
