In control theory, a time-invariant (TIV) system has a time-dependent system function that is not a direct function of time. Such systems are regarded as a class of systems in the field of system analysis.The time-dependent system function is a function of the time-dependent input function.If this function depends only indirectly on the time-domain (via the input function, for example), …
