在simulink仿真中报错，提示说multiport switch有错，提示信息如下，敬请高手帮忙

The control input must be greater than or equal to 1 and less than or equal to the number of inputs if using one-based indexing; The control input must be greater than or equal to 0 and less than the number of inputs if using zero-based indexing

不懂，呵呵。
不过看错误信息，貌似是输入的参数错误。

你给multiport switch 模块的输入不在其可接受范围。检查一下你给他的那个整数，与它可接受的范围是否匹配。
