我 在非线性控制的仿真中遇到这样的一个问题, Derivative input 1 of 'xingqier3/Simplified Synchronous Machine pu Units/Source/Z/Integrator3' at time 0 is Inf or NaN. Stopping simulation. 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)请问对于出现这种问题如何解决呢
以下有我的仿真图和初始值,请高手给于指点,
