【Abstract】 The decoupling internal model control(IMC) was investigated for multivariable stable processes with different time delays.And this method was extended and applied to a conventional PID control of DCS equipment by IMC-PID transform.All the stabilizing IMC controllers and the resulted closed-loop systems were characterized in terms of the open-loop system’s time delays.The method has an advantage of being simple and easy to realize for the optimization and APC control of a complex process system like a rectification.更多还原
