Abstract :
Properties of a plant input generated by a properly designed feedback control system are studied based on the transfer function from the reference input to the plant input. The effects of poles of the plant and the closed-loop system on the plant input are studied for the first order case of this transfer function subjected to a step reference input Introducing the concept of virtual plant poles, the results are then extended to the second-order case for an over-damped closed-loop system.
