This article proposes a novel control strategy considering the efficiency optimization and dynamic improvement for dual-side LCC compensated wireless permanent magnet synchronous motor (PMSM) system with variable dc-link voltage. First, the dc-link voltage is added as a control variable to reduce the losses of three-phase converter. According to the variable dc-link voltage, the designing guidance about parameters of dual-side LCC compensation networks is given. Moreover, an extended state observer based voltage calculation method, robust to the parameter mismatch, is designed to obtain the minimum dc-link voltage reference required by PMSM system. A finite-control-set model-free predictive control is proposed for regulating the dc-link voltage to quickly track the reference. Furthermore, an adaptive perturbation and observation method is presented to improve the system efficiency, and the cooperative control principle of wireless PMSM system is given. Finally, the capability of proposed strategy is verified by experimental results.
