【Abstract】 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.更多还原
