本文阐述了二自由度系统的类型及应用价值,推出了基本运算为不完全微分PID的滤波型二自由度控制算法,它具有结构简单、参数整定容易、比常规PID控制器性能优越等特点。文中给出了采用M_(51)B单片机实现该算法的应用例——电炉温度二自由度PID控制系统。
This paper describes the type of two degrees of freedom system and its application value, and introduces a two-degree-of-freedom control algorithm based on incomplete differential PID. It has the advantages of simple structure, easy parameter tuning and superior performance compared with conventional PID controller. In this paper, M_ (51) B microcontroller is used to achieve the application of the example - temperature furnace two degrees of freedom PID control system.
