摘要
用传统的根轨迹法设计反馈控制系统的串联校正装置是用手工方式通过图解方法进行的。本文提出的线性定常系统串联校正的设计方法,虽然也是以系统根轨迹为基础,但却是一种解析设计方法,串联校正装置的参数通过极点公式和零点公式解析求解得到,而不需要绘制根轨迹图,设计过程非常简便,特别适合于计算机求解。文中推导了串联校正装置的极点公式和零点公式,给出了设计步骤和程序框图,并通过实例说明了这种方法是可行的。
The conventional approach to design a series compensator of a feedback control system based on the root-locus method is a graphical and manualone. In this paper a new apprach to design the series compensator is present-ed. It, although based on the root locus too, is a kind of anslytic Approachto design, the parameters of the series compensator are determined from thepole and zero formulae. Dcsign procedure is very easy, need not sketch theroot-locus plot, and this approach is very easy, need not sketch theputer. In the paper, the pole and zero for mulae of the series for solving by com-deduced. Design procedures and the program chart is given. This approachis proven feasible by the examples.
