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 ( ?+ @6 k" D7 STrustRegion-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.7 H$ v8 x6 U! Q

If the error persists in spite of the above changes, then the model is likely ill-defined and requires modification.
