Abstract

The main objective is to provide the system robustness and improved overall performance
under significant model mismatches. In this a novel engineering oriented control system
design methods for multivariable processes is presented. By employing the concepts of
energy transmission ratio and effective relative gain, an Equivalent and Effective transfer
function matrices for closed loop control system can be obtained. Consequently, the
decentralized controllers can be independently designed by employing the single loop
tuning techniques. These two design methods provide simple, straight forward and easy
approaches for better computation. The real time experimentation carried out for the
lower order MIMO process using VUDAQ-100 adds on card. The designed decentralized
controllers are applied and the performances of both the methods have been analyzed.
