Interacting system in process control

Discusses the differences between interacting and non- interacting processes. Made by faculty at Lafayette College and produced by the University of Colorado . Transfer Function for an R-C Systems - Duration: 9:01. We used that model to predict the open-loop process behavior and its closed-loop behavior, under feedback control. In this lesson, we complicate the process , and .

Derivation of process model from first principles is often difficult due to its complexity.

The first stage in the development of any control and monitoring system is the identification and modeling of the system.

Consider two liquid storage tanks in series.

They can be arranged in two fashion, viz. Department of Instrumentation and Control , Atmiya Institute of Technology and Science, Rajkot, India. Abstract: The control of liquid level in tank system and flow between tanks is main problem in process industries like petroleum.

An experimental setup of three tank level process in interacting and non- interacting mode was studie to obtain the process models.

Different control schemes such as. Internal model controller (IMC), IMC-PID and Proportional –Integral and Derivative (PID) were . Only the amplitude ratio is presented here, because more extensive frequency response analysis is presented in Chapter 1 where the im portance of the phase behavior on stability is demonstrated and applied in control system analysis. A process is truly multi-capacity when it has . Control of the level in the tank and flow in between them is basic problem in process control industries almost all . The first stage is in the development of any control and monitoring system is the identification of the system and mathematical modelling of the system.

The process is said to be interacting if: Each input affects more than one output. The present work is on the mathematical model for interacting and non- interacting tank process with disturbances.

PSO gives better and satisfactory response than fuzzy controller. Keywords: Fuzzy logic controller , PID controller , Particle swarm optimization, Two tank non- interacting liquid level system. The controls of liquid level in multiple tanks and flow between the tanks are basic problems in the process industries.

The control system is intended to maintain the level of the third tank at some predefined value irrespective of changes of inflow of first tank.

Develops the transfer functions to describe an interacting process.
