[Simulink相关] 这个问题咋样解决

[tangxy03]

错误是：Algebraic state in algebraic loop containing block 'LQR_control/Sum2' computed at time 0 is Inf or NaN. There may be a singularity in the solution. If the model is correct, try reducing the step size (either by reducing the fixed step size or by tightening the error tolerances)
