Decoupling Control of Headbox using Particle Swarm Optimisation (PSO) Algorithm

For multivariable systems, loop interaction is a major issue to be addressed. To reduce loop interaction among various loops in a multivariable system, decouplers are designed. Decouplers act as cross controllers for any multivariable systems. The control of such systems using decouplers, is known as decoupling control. The objective of decoupling control is to minimize control loop dealings. This paper presents design and analysis of decoupling control of headbox using PI controller based on Particle Swarm Optimisation (PSO) algorithm. The performance of PSO based PI controller has been compared with PI controller designed using conventional techniques such as IMC, ZN and TL.
