In this paper we consider the behavior of the output of a multivariable feedback system at the beginning of the response when inputs are a polynomial function of time.
It is shown that this initial behavior can be computed very easily from the open-loop transfer function matrix of the system. Using this result, so called “a reverse response” to a step function input in scalar systems is extended to the case of multivariable systems, and conditions that a feedback system has no reverse response to any vector step function are obtained.
