求问:在mworks里实现simulink的buck模型
一般问题

如图一是simulink里面带PI反馈控制的BUCK降压电路，已验证能够成功运行。我想在mworks里同样搭建该模型，但是点击仿真时遇到如图所示错误，请问应该如何解决？
其中，图二是mwork中buck整体图，图三是pi控制子系统，图四是错误。

您好，这个问题是此组件缺少输入，所以显示报错。
您可以将该组件替换为Modelica.Electrical.PowerConverters.DCDC.Control.SignalPWM，并将该组件useConstantDutyCycle参数设置为true
您也可以根据 PWM Generator (DC-DC)基本原理，基于Modelica语言进行自主开发
