摘要:
为了提高系统的可靠性,针对系统中的功率管和位置传感器等脆弱环节,提出一种容错逆变器-永磁同步电动机无位置控制系统结构。系统中的逆变器采用容错拓扑结构,由四开关实现逆变器器件开路故障后的容错运行;自适应滑模观测器用于估算电机转子位置和转速,实现永磁同步电动机的无位置传感器控制。为减少四开关逆变器的输出谐波,对其SVPWM控制策略进行研究分析。对故障前后运行状况进行对比,仿真和实验结果证明所提出系统能够实现功率管开路故障后的可靠运行。
Abstract:
In order to improve reliability,a new fault-tolerant inverter based permanent magnet synchronous motor(PMSM) position sensorless control system is proposed to avoid fragile parts of power components and position sensor.The fault-tolerant inverter topology was adopted and its four switches were used to maintain running when an open-switch fault happened.Sensorless control of PMSM was implemented by means of an adaptive sliding mode observer(SMO).Space vector pulse width modulation of four-switch inverter was...
