摘　　要：对考虑铁损时感应电机在同步旋转坐标系统下的数学模型进行了分析。在分析基础上,通过研究不同运行条件下电机损耗与转子磁通的关系,实现了矢量控制变频调速感应电机(IM)的优化控制。为了进一步提高电机的调速性能,根据电机矢量控制的基本原理,利用数字信号处理器(DSP)和智能功率模块(IPM),给出了矢量控制硬件的实现;阐述了系统的软件实现方法。实验表明,矢量控制变频调速系统能平稳运行,具有较好的静、动态特性,可以广泛用于以IM为驱动装置的电气传动系统中。Taking the iron loss into account based on the mathematic model of induction motor in rotate coordinate, studying the relation of the motor loss and the rotor flux in different contions,the optimal control for the vector control system of the induction machine was realized.In order to get much better performance,the basic vector control principle of asynchronous motor was analysed, and a scheme of vector control using DSP and IPM for system was proposed, fhe structure of the system control and the software design method are introduced in detail.The experiment shows the system has good static and dynamic performances and the system can be used widely in electric drive system with asynchronous motor.
