50、型是很困难的。为了简化永磁同步电机的数学模型，我们通常做如下假设：忽略电机的磁路饱和，认为磁路是线性的；不考虑涡流和磁滞损耗；当定子绕组加上三相对称正弦电流时，气隙中只产生正弦分布的磁势，忽略气隙中的高次谐波；驱动开关管和续流二极管为理想元件；忽略齿槽、换向过程和电枢反应等影响。永磁同步电机的数学模型由电压方程、磁链方程、转矩方程和机械运动方程组成，在两相旋转坐标系下的数学模型如下：(l)电机在两相旋转坐标系中的电压方程如下式所示:其中，Rs为定子电阻；ud、uq分别为d、q 轴上的两相电压；id、iq分别为d、q轴上对应的两相电流；Ld、Lq分别为直轴电感和交轴电感；c为电角速度；d、q分别

51、为直轴磁链和交轴磁链。若要获得三相静止坐标系下的电压方程，则需做两相同步旋转坐标系到三相静止坐标系的变换，如下式所示。(2)d/q轴磁链方程：其中，f为永磁体产生的磁链，为常数，而是机械角速度，p为同步电机的极对数，c为电角速度，e0为空载反电动势，其值为每项绕组反电动势的倍。(3)转矩方程：把它带入上式可得:对于上式，前一项是定子电流和永磁体产生的转矩，称为永磁转矩；后一项是转子突极效应引起的转矩，称为磁阻转矩，若Ld=Lq，则不存在磁阻转矩，此时，转矩方程为：这里，为转矩常数，。(4)机械运动方程：其中，是电机转速，是负载转矩，是总转动惯量(包括电机惯量和负载惯量)，是摩擦系数。直线电机原

52、理永磁直线同步电机是旋转电机在结构上的一种演变，相当于把旋转电机的定子和动子沿轴向剖开，然后将电机展开成直线，由定子演变而来的一侧称为初级，转子演变而来的一侧称为次级。由此得到了直线电机的定子和动子，图1为其转变过程。直线电机不仅在结构上是旋转电机的演变，在工作原理上也与旋转电机类似。在旋转的三相绕组中通入三相正弦交流电后，在旋转电机的气隙中产生旋转气隙磁场，旋转磁场的转速（又叫同步转速）为： （1-1）其中，交流电源频率，电机的极对数。如果用表示气隙磁场的线速度，则有： （1-2）其中，为极距。当旋转电机展开成直线电机形式以后，如果不考虑铁芯两端开断引起的纵向边端效应，此气隙磁场沿直线运动方

53、向呈正弦分布，当三相交流电随时间变化时，气隙磁场由原来的圆周方向运动变为沿直线方向运动，次级产生的磁场和初级的磁场相互作用从而产生电磁推力。在直线电机当中我们把运动的部分称为动子，对应于旋转电机的转子。这个原理和旋转电机相似，二者的差异是：直线电机的磁场是平移的，而不是旋转的，因此称为行波磁场。这时直线电机的同步速度为v=2f,旋转电机改变电流方向后，电机的旋转方向发生改变，同样的方法可以使得直线电机做往复运动。图1永磁直线同步电机的演变过程 图2 直线电机的基本工作原理 对永磁同步直线电机，初级由硅钢片沿横向叠压而成，次级也是由硅钢片叠压而成，并且在次级上安装有永磁体。根据初级，次级长度不同

54、，可以分为短初级-长次级结构和长初级-短次级的结构。对于运动部分可以是电机的初级，也可以是电机的次级，要根据实际的情况来确定。基本结构如图3所示，永磁同步直线电机的速度等于电机的同步速度： （1-3）图3 PMLSM的基本结构 矢量控制（磁场定向控制技术）矢量控制技术是（磁场定向控制技术）是应用于永磁同步伺服电机的电流（力矩）控制，使得其可以类似于直流电机中的电流（力矩）控制。矢量控制技术是通过坐标变换实现的。坐标变换需要坐标系，变化整个过程给出三个坐标系：静止坐标系（a，b，c）：定子三相绕组的轴线分别在此坐标系的a，b，c三轴上；静止坐标系（，）：在（a，b，c）平面上的静止坐标系，且轴与

55、a轴重合，轴绕轴逆时针旋转90度；旋转坐标系（d,q）:以电源角频率旋转的坐标系。矢量控制技术对电流的控制实际上是对合成定子电流矢量的控制，但是对合成定子电流矢量的控制的控制存在以下三个方面的问题：是时变量，如何转换为时不变量？如何保证定子磁势和转子磁势之间始终保持垂直？是虚拟量，力矩T的控制最终还是要落实到三相电流的控制上，如何实现这个转换？从静止坐标系（a，b，c）看是以电源角频率旋转的，而从旋转坐标系（d,q）上看是静止的，也就是从时变量转化为时不变量，交流量转化为直流量。所以，通过Clarke和Park坐标变换（即3/2变换），实现了对励磁电流id和转矩电流iq的解耦。在旋转坐标系（d,q）中，已经成为了一个标量。令在q轴上（即让id=0），使转子的磁极在d轴上。这样，在旋转坐标系（d,q）中，我们就可以象直流电机一样，通过控制电流来改变电机的转矩。且解决了以上三个问题中的前两个。但是，id、iq不是真实的物理量，电机的力矩控制最终还是由定子绕组电流ia、ib、ic（或者定子绕组电压ua、ub、uc）实现，这就需要进行Clarke和Park坐标逆变换。且解决了以上三个问题中的第三个。力矩回路控制的实现：图中电流传感器
