| 摘 要： | 针对传统永磁同步电机(PMSM)驱动系统存在的问题,应用一种连续型开关升压逆变器,通过应用预测控制方法提高PMSM控制性能。拓扑电路在逆变电路和输入直流电源之间加入一个开关升压电路,以达到提高系统电压增益和消除死区的目的,同时可使系统具有更高的可靠性。此外,采用预测电流控制(PCC)方法对PMSM进行控制,与传统的矢量控制技术相比,PCC具有更快的动态响应,并减少了电流脉动。最终,通过试验验证了基于开关升压变换器的PMSM PCC的可行性。

| Abstract: | A type of continuous switched boost inverter was used to improve the control performance of permanent magnet synchronous motor (PMSM) through predictive control, aiming at the drawback of the traditional PMSM drive system. By adding a switched boost circuit between the inverted circuit and input DC power, switched boost inverter circuit was formed to achieve higher voltage gain and eliminate the dead zone. Meanwhile, the drive system had higher reliability. Moreover, predictive current control (PCC) was adopted to control PMSM. In comparison with the traditional field oriented control, PCC had faster dynamic response and could reduce current ripple. Finally, experiment results verified the feasibility of the predictive current control for PMSM based on the continuous switched boost inverter. |
