Question: An inverse response (right-half-plane zero) in the feedback process dynamics in a single-loop control system was analyzed Assume that a two-input-two-output process has monotonic step responses for each input-output relationship. Discuss whether the 2 x 2 closed-loop control system can have an inverse response in one controlled variable, and if so, under what conditions. If yes, discuss how this situation may affect the control performance of the system.
