摘　　要：针对无人机中舵机用电机大功率、高转矩、高可靠性的要求,对五相永磁同步电机(PMSM)驱动系统矢量控制策略进行了研究。建立了五相PMSM在自然坐标系下的数学模型,并通过Clark、Park变换,推导出两相坐标系、旋转坐标系下的数学模型,进而设计双平面矢量控制策略,该策略能够同时控制电机的基波和三次谐波电流,以优化电机的性能。针对五相SVPWM调制方法,传统的相邻最大两矢量合成目标矢量时会伴生三次谐波电压,于是提出采用改进的相邻四矢量合成方法,通过控制基波平面电压矢量及其作用时间有效抑制了伴生三次谐波电压。在Simulink下搭建了五相PMSM矢量控制系统仿真模型,对算法进行了仿真研究。然后搭建了五相PMSM实验平台进行实验验证,实验结果说明了本文算法的有效性和实际可行性。To address the stringent demands on motors used in UAV steering engines—requiring high power,substantial torque,and exceptional reliability—a vector control strategy was explored for a drive system utilizing a five-phase permanent magnet synchronous motor(PMSM).Established a five phase PMSM mathematical model in a natural coordinate system,through Clarke and Park transformations,mathematical models in the two-phase and rotating coordinate systems have been derived.Subsequently,a dual-plane vector control strategy has been designed,capable of concurrently controlling the fundamental and third-harmonic currents of the motor to optimize its performance.For the five phase SVPWM modulation method,the traditional adjacent maximum two vector synthesis target vector will be accompanied by a third harmonic voltage.Therefore,an improved adjacent four vector synthesis method was proposed to effectively suppress the associated third harmonic voltage by controlling the fundamental plane voltage vector and its duration.A simulation model of a five phase PMSM vector control system was built in Matlab/Simulink,and the algorithm was simulated and studied.Then a five phase PMSM experimental platform was built for experimental verification,and the experimental results demonstrated the effectiveness and practical feasibility of the algorithm proposed in this paper.
