A process is described by the transfer functionwhich includes actuator and measurement dynamics. The process engineering group has the option of redesigning the process to eliminate the right-half plane zero. They need to determine whether this modification will yield a substantially better (faster) controlled process.(a) For a proportional-only controller, find the stability bounds for K for the existing process.(b) Repeat part (a) for the case where the RHP zero has been eliminated.(c) From analysis and/or your knowledge of closed- loop systems, what can you say about the potential speed of response of this controlled process if the zero can beeliminated?
