在晶闸管上并联了一个MOA，结果运行后出现了以下错误，请高手解答啊？谢谢了 o8 @4 K! \" |" w
TrustRegion-based algorithm due to one of the following reasons: the model is ill-defined i.e., the system equations do not have a solution; or the nonlinear equation solver failed to converge due to numerical issues. 3 P9 H4 E0 }9 \0 E! B9 D1 NTo rule out solver convergence as the cause of this error, either ; L( r9 g7 r% E# B$ Oa) switch to LineSearch-based algorithm using 7 A% u5 S5 T4 M F2 Oset_param('power_svc_1tcr3tsc','AlgebraicLoopSolver','LineSearch')6 W& a0 _- F# J( r- D
b) reducing the VariableStepDiscrete solver RelTol parameter so that the solver takes smaller time steps.. u6 L/ U; \8 w# n2 M/ R
If the error persists in spite of the above changes, then the model is likely ill-defined and requires modification.
