Simulink仿真报错奇点(singurlity)问题

2017-10-02 15:37 267 查看
Simulink仿真时报错如下:

给出的解决方法是减小步长

Derivative of state ‘1’ in block ‘PID_2huiluqiehuan_turbojet/折合流量增益 输出为pi/State Space’ at time 2.0548468687279264 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)

换了多个求解器仍然报错,这时若报错的系统中有PID,则可以在回路中加入限幅
