精选示例
非线性电感器
此示例展示了非线性电感器的实现，其中电感取决于电流。tanh 函数定义非线性磁通-电流关系。磁通会在较大的电流下饱和，例如，在铁芯电感器中会出现这种情况。
电磁铁
此示例展示了一个带有弹簧复位的电磁铁。该电磁铁被建模为一个电感，其值 L 取决于柱塞位置 x。时变电感的反电动势为：
Heat Sink Using PS State-Space Block
How the PS State-Space block can be used to model a heat sink in air. The heat sink is modeled as rods with distributed masses along the length of the rods fixed to a base. The rods extend from the surface that undergoes conduction along its length and convection with air in the direction perpendicular to its length.
