Discussion on Muskingum versus Integrator-Delay Models for Control Objectives

Step closed-loop response for the case I: downstream flow with PI designed by discrete Muskingum (ZOH,  s) with continuous Muskingum plant; case II: downstream flow with PI designed by discrete Muskingum (ZOH,  s) with continuous Muskingum plant; case III: downstream flow with PI designed by discrete Muskingum (ZOH,  s) with continuous ID plant; case IV: downstream flow with PI designed by discrete Muskingum (ZOH,  s) with continuous ID plant; and case V: downstream flow with PI designed by continuous Muskingum with continuous Muskingum plant.
