:'( 本人做的是模糊 PID仿真,运行时总出现以下提示,输入信号为阶跃响应,运行到1s时就无法进行了出现以下提示,输入正弦信号就可以正常运行,不知道问题出在哪
Warning: Next step size (3.552713678801045e-015) is smaller than minimum step size (4e-015) at time 1.000000000000157 because distance between zero crossings is smaller than the minimum step size.
Warning: Unable to reduce the step size without violating a minimum step size of 3.552713678801162e-015 at time 1.000000000000193 for model 'untitled'.
Warning: Unable to reduce the step size without violating a minimum step size of 3.552713678801275e-015 at time 1.000000000000224 for model 'untitled'.
希望大家帮帮忙
