Generally, setting “Sample Time” in “If-Action” subsystems is not recommended as it can cause sample rate transition to be implicitly mixed up with block algorithms. This can often lead to ambiguity and confusion in Simulink models. The below link can provide more information on this:
To set “Sample Time” for the ‘If” block, all blocks in the “If-Action” subsystem must execute at the same rate as the driving “If” block. To meet this requirement, set the “Sample Time” for each block to either inherited (-1) or the same value as the “If” block sample time, which seems to be 0.02 in this case. For details on the execution of an “If-Action” subsystem, you can refer to the documentation:
Hope this is useful to you.
