three state controller

A three-loop system is constructed for a vector control permanent magnet linear synchronous motor ( PMLSM). In the speed-loop and current-loop, an IP controller and a state feedback controller are used for high accuracy and rapid tracking and to restrain disturbance.

把一矢量控制的永磁直线电机构成一个三环系统，在速度环和电流环内采用IP速度控制器和状态反馈控制器，以实现电机的高精度快速进给，并抑制外部扰动对系统的影响。

Chapter three introduces the GPIB controller interface function, especially the designing of state machine according to IEEE-488.Chapter four introduces the designing of data channel.

第三章详细阐述了GPIB控制器的十种接口功能及其状态机实现，完全遵循IEEE-488协议规范。第四章对数据通路进行了较为细致的说明。
