说明：  探究粒子群算法对电机的估计，具有重要意义。(It is important to explore the estimation of the motor by particle swarm.)

说明：  异步电机矢量控制，异步电动机具有非线性、强耦合、多变量的性质，要获得高动态调速性能，必须从动态模型出发，分析异步电动机的转矩和磁链控制规律，研究高性能异步电动机的调速方案。矢量控制系统和直接转矩控制系统是已经获得成熟应用的两种基于动态模型的高性能交流电动机调速系统。矢量控制系统通过矢量变换和按转子磁链定向，得到等效的直流电动机模型，然后模仿直流电动机的控制策略设计控制系统。(Vector control of asynchronous motor, asynchronous motor has the characteristics of non-linear, strong coupling and multi variable. In order to obtain high dynamic speed regulation performance, we must start from the dynamic model, analyze the torque and flux control law of asynchronous motor, and study the speed regulation scheme of high-performance asynchronous motor. Vector control system and direct torque control system are two kinds of High-Performance AC motor speed control system based on dynamic model, which have been widely used. The vector control system obtains the equivalent DC motor model through vector transformation and rotor flux orientation, and then designs the control system by imitating the control strategy of DC motor.)
