摘　　要：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P ID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.Based on the importance of extracting differential signal in industry and aerospace control, an adaptive high order differential feedback controller （AHODFC）, which is capable to extract high-quality differential signals and can be 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, and easier to adjust parameters,which demonstrates that AHODFC has practicability and feasibility.
