基于DSP技术的交流伺服运动控制系统

　　本文旨在为普通的交流异步电机开发一套伺服系统。交流感应电机因其结构简单，价格低廉，维护方便，并且通过采用先进的控制技术可具备良好的静、动态性能，因而在高性能伺服驱动系统中广泛应用。伺服驱动系统需要快速的动态响应，良好的抗干扰能力以及对参数变化具有鲁棒性，而影响这些因素的关键之一就是位置/速度传感器。所以，电机无位置/速度传感器控制己成为一个研究的热点。

　　本文以ADI公司的BF506 EZ-KIT为核心，采用转子磁场定向矢量控制(FOC)理论，以及扩展的卡尔曼滤波(EKF)算法，设计了一种基于DSP的无位置传感器伺服感应电机矢量控制系统。伺服系统软件由位置环、速度环和电流环组成，在异步电机矢量控制原理的基础上设计了控制系统的速度环及电流环，以实现闭环控制。如果在电机系统中加入传感器，不但增加了系统的成本和安装的困难，而且降低了系统的机械鲁棒性，阻碍了电机向高速化、小型化的发展，因此，无传感器技术的研究具有重要的实际意义。

　　According to DSP technical of exchanges servo sport control system

　　Along with flying of calculator technique soon development and exchanges electrical engineering adjust to soon and technically fly soon develop, modern communicates that the development of servo system changes with each passing day, various control method with adjust soon means can apply actual control system in, make modern and servo system toward small scaled turn, the intelligence turns, the direction of the high-speed high accuracy development, this text aim at for common of the exchanges difference tread electrical engineering to develop a set of servo system. The exchanges responds electrical engineering because its structure is simple, the price is cheap, supporting convenience, and passing the control technique of adopting the forerunner can have good quiet, dynamic state function, as a result servo drive system in the high performance in extensive application. Servo the demand rapid dynamic state driving system respond to, good anti- interference ability and have Lu stick to the parameter variety, but influence one of the key of these factors is a position/speed to spread a feeling machine. So, the electrical engineering has no position/speed to spread a feeling machine control F become the hot point of a research.
