Simulation studies for delay effect on stability of a canonical tank process

Abstract

Whenever the propagation of material or energy is modeled, dead time naturally comes into picture in the majority of the industrial process models. The existence of dead time is every time a great apprehension to the process industry. There are various limitations and constrains on the design of controllers, may be classical or intelligent, in the presence of delay time. Its presence also affects stability of the system. The present control system analysis focuses on the effect of dead time on stability of the selected process which can be modeled as first-order plus dead time model.
