Derivative of state ‘1‘ in block ‘untitled/PID/Integrator‘ at time 0.0 is not finite.

问题

对一个控制系统进行simulink仿真时出现错误、错误显示为“Derivative of state ‘1’ in block ‘Simulin/Controller Subsystem/Integrator’ at time 0.84166799753954546 is not finite. The simulation will be stopped. There may be a singularity in the solution. If not, try reducing the step size (either by reducing the fixed step size or by tightening the error tolerances)”

解决方法

针对类似仿真系统中的积分环节出现上述错误，我们采用在仿真界面按下快捷键ctrl+E呼出如下界面，然后设置
== Start time value is than 0==即可解决报错问题。
