Controller for Multivariable Processes Based on Interaction Approach

摘要

In real time environment most of the industrial processes are posses 'n' number of inputs, and outputs. Due to intrinsically nonlinear nature and interactions existing among the loops, it is very complicated to design a control strategy for multivariable processes. Tuning of Conventional PID controller for multivariable process is too difficult. This paper utilizes the concept of IMC to determine parameters multivariable PID controller. A case study was included to describe the effectiveness of proposed method.
