摘要
电动汽车使用的IPMSM电机更多工作于转矩控制,有驱动和制动两种工况。矢量控制下的转矩控制核心是高性能控制目标下i_(d),i_(q)电流的分析与计算,常用解析法、图形法及查表法等。为此,需基于电机工作特性进行控制区间的划分及控制策略的开发,可看出驱动和制动工作下各参数的参考关系,为工程实施和进一步研究提供参考和方向。
The torque control of IPMSM is worked more in the EV, including driving and braking. Using torque control under vector control, the core is the analysis and calculating i_(d), i_(q) by analytic and graphical methods or look-up table for the high performance. It is necessary to divide the control interval and develop the control strategy based on the working characteristics of the motor, and the reference relationship of parameter between driving and braking can also be found, providing reference and direction for project implementation and further research.
