| Based on three-phase eight-switch inverter, a novel sensorless finite-control-set model predictive control
(FCS–MPC) strategy is proposed for the permanent magnet synchronous motor (PMSM) drive system with fractionalorder
sliding-mode observer. Firstly, the mathematical models of three-phase eight-switch inverter and permanent magnet
synchronous motor (PMSM) are established by the operating mode of a driving system. Secondly, by using the technique of
fractional-order sliding-mode observer, an observer is constructed to realize fast and accurate real-time estimation of system
speed and counter electromotive force. Finally, using improved FCS–MPC strategy to reduce the calculation amount and
electromagnetic torque ripple of the control system. Meanwhile the fault tolerant control with current feedback characteristic
provided by the method can effectively suppress the adverse effect resulting from the two capacitor voltage’s unbalance
of DC bus terminal in three-phase eight-switch inverter. The simulation results demonstrate that the proposed method can
enable whole system to not only run reliably and stably, but also achieve satisfactory dynamic performance as well as lower
