计算机求取自动控制系统的单位阶跃响应的方法很多、但求取一个自动控制系统的单位脉冲响应则很少见到。这里介绍一种在用四阶龙格—一库塔法求取了控制系统单位阶跃响应的基础上,采用三次样条函数来求取该系统的单位脉冲响应的方法。该算法用BASIC语言编写的程序,在APPLE——Ⅱ微型机上通过,效果良好。 There are many ways to calculate the unit step response of the automatic control system by computer. However, the unit impulse response of an automatic control system is seldom seen. Here a method of using the fourth order Runge-Kutta method to obtain the step response of the control system unit, using the cubic spline function to obtain the unit of the impulse response of the system. The algorithm written in BASIC language, passed on APPLE - Ⅱ microcomputer, the effect is good.
