“…PMSM is a nonlinear system [92], and although the parameter setting of the linear sliding mode control (LSMC) is very simple [75], but the control ability is limited in complex nonlinear environments, unable to achieve high-performance control of the system. Considering that the introduction of non-linear terms may lead to better performance [93], so many scholars both domestically and internationally have redirected their research attention toward exploring the realm of nonlinear sliding mode surfaces.…”

With the increasingly widespread application of permanent magnet synchronous motors (PMSMs), it is required that PMSM can still maintain high efficiency and high reliability in complex environments. Due to the nonlinearity of PMSMs and the influence of external disturbances, its precise control is still a challenge. As a modern control scheme, sliding mode control can improve the control PMSM drive system. It has been successfully applied in the control of PMSMs and has become a hot spot in the motor drive system. This paper provides an overview of the current research status of sliding mode control strategies based on PMSMs and introduces the design of sliding mode controllers, as well as the development and application of high-order sliding mode control. The method of suppressing the chattering problem is summarized, and the deficiencies of it are put forward. Finally, the development trend of sliding mode control technology is discussed, and the future development direction of SMC for PMSM is prospected.

“…[12][13][14][15][16][17] In recent years, model predictive control (MPC) has been regarded as a powerful alternative to FOC because of its simple principle, easy of dealing with multiple constraints, and fast dynamic response. [18][19][20][21] According to different control variables, MPC can be divided into predictive current control, [22][23][24] predictive torque control, 25,26 and predictive speed control, 27,28 among which predictive current control is widely used because there is no adjustment of the weighting factor. According to whether the modulation scheme is adopted or not, MPC can be divided into finite control set model predictive control (FCS-MPC) 29,30 and continuous control set model predictive control (CCS-MPC), 31 wherein FCS-MPC can calculate the optimal voltage vector by minimizing the cost function and directly act on the inverter, and it is easy to add constraints, which is more concise.…”

Traditional finite control set model predictive control (FCS-MPC) selects an optimal voltage vector in one control cycle. However, considering multiple control cycles, it cannot be proved that the voltage vector is optimal, and the uncertainty of PMSM parameters seriously affects the prediction accuracy. In order to balance the relationship between switching frequency, steady-state performance, and robustness, a multi-step robust FCS-MPC is proposed. Firstly, an incremental prediction model is established to eliminate the flux linkage of permanent magnets. The inductance parameters in the incremental model are identified online based on the observer and inductance extraction algorithm. Then, based on the principle of no-beat, the candidate voltage vector in two control periods is simplified to get the candidate voltage vector, and the cost function is used to determine the optimal voltage vector again. Finally, the proposed FCS-MPC method is compared with the traditional FCS-MPC method. The experimental results show the effectiveness of FCS-MPC strategy.

This paper addresses a novel sliding mode control based on state observer for active magnetic bearing rotor system. Firstly, the state-space model of a radial AMB rotor system is established with considering unbalance disturbance and gyro effect for a vertical flywheel energy storage system. Then a sliding mode function and switching surface are constructed based on an observer. Meanwhile, a separation and decoupling strategy based on Finsler’s lemma is proposed. Through this method, the constraint relationship between the controller gain, active magnetic bearing matrices and the Lyapunov variables is eliminated. After that a method for chattering reduction in the sliding-mode controller is raised. Relied on these techniques, new sufficient conditions for the stability of AMB rotor system are given in the framework of linear matrix inequalities. Finally, the effectiveness of the proposed sliding mode controller is validated on the experimental platform of the flywheel energy storage system.
