Abstract  Based on the importance of extracting differential signal in industryand aerospace control, an adaptive high order differential feedback controller (AHODFC), which is capable to extract high-quality differential signals and canbe applied to AC adjustable-speed system with varying frequency, is presented.Since in engineering application, it is easy to implement interface operation, data acquisition and port operation by VC++, VC++ is adopted to implement the control interface of AC adjustable-speed system with varying frequency. In addition, programming process of high-order differential controller algorithm is proposed as well as the interface operation of this adjustable-speed system. Through simulation and practical running, comparing with PID control, high-order differential feedback control has better control effect and robustness, andeasier to adjust parameters, which demonstrates that AHODFC has practicability and feasibility.

Key words： high order differentiator      high order differential feedback controller      adaptive high order differential feedback controller      AC adjustable speed system with varying frequency

AHODFC在交流调速中的应用及其软件实现

基于提取微分信号在工业控制及航天控制中的重要作用，介绍了一种可提取高品质微分信号的自适应高阶微分反馈控制器(AHODFC)，并将其应用于交流调速系统中。考虑到在工程应用中，VC++易于实现交互界面、数据采集和端口操作等操作，基于VC++平台编制了该调速系统的控制界面，并介绍了高阶微分控制器算法的编程过程，还详细介绍了该调速系统的控制界面操作。通过仿真运行和实际系统的运行，证明高阶微分反馈控制与PID控制相比，具有控制效果好，参数调节容易，鲁棒性能好等特点，具有可行性及实用价值。
