基于C/S结构的远程电机控制系统设计

近年来，网络技术的不断进步，为远程控制技术的发展创造了条件。以MsAccess为数据库，通过使用MFCODBC技术访问数据库的编程方法实现底层变频器参数的设定和电动机运行数据的读取。分析了带有Smith顸估补偿器的PID控制算法，系统选择了计算机的RS485接口来进行通信。用户通过服务器端RS485接口和变频器串行I／F基板（ISI）进行串行通信，利用变频器对交流电动机进行了良好的控制。

Design of Remote Motor Control System based on the C/S Structure

In recent years, the rapid development of network technology has made it possible for the development of remote control technology. It can send the parameter to the transducer and receive parameter from the electromotor through the Ms Access database by the technique of MFC ODBC. Analyze the PID control arithmetic which comprises smith estimation. We choose the interface of RS485 for controlling more than one electromotor. And the electromotor can be well controlled by transducer by the serial communicating between RS485 and the ISI of transducer.
