【摘要】：永磁磁通切换电机是一种新型定子励磁型电机,在无刷直流发电领域具有潜在应用前景。为解决脉宽调制整流装置因加装位置传感器而带来的成本增加、系统运行可靠性下降等问题,采用单周期控制技术作为无位置传感器直流发电系统的基本控制策略。针对传统单周期控制策略存在的反电动势与电枢电流基波相移问题,采用了一种基于双积分器注入虚拟滞后电流的改进控制策略,并详细推导了核心控制方程。结合简化小信号模型给出的电压开环传递函数,直接采用相位裕度分析法得到了电压控制器参数,较常用的根轨迹设计法更为直观、便捷。750 W样机的仿真与试验结果验证了分析方法的正确性和有效性。
[Abstract]:Permanent magnet flux switching motor is a new type of stator excitation motor, which has potential application in brushless DC power generation field. In order to solve the problems of increasing the cost and decreasing the reliability of the system when the position sensor is installed in the pulse width modulation rectifier, the single cycle control technique is adopted as the basic control strategy of the sensorless DC power generation system. In order to solve the problem of phase shift of fundamental wave of backEMF and armature current in traditional single period control strategy, an improved control strategy based on injecting virtual hysteresis current into dual integrator is adopted, and the core control equation is deduced in detail. Combined with the voltage open-loop transfer function given by the simplified small-signal model, the parameters of the voltage controller are directly obtained by phase margin analysis, which is more intuitive than the common root trajectory design method. The simulation and test results of convenient .750 W prototype verify the correctness and effectiveness of the analysis method.
