This paper presents a new design of robust optimal controller for multivariable system. The row characteristic functions of a linear multivariable system and dynamic decoupling of its equivalent system, were applied to change the transfer function matrix of a closed-loop system into a normal function matrix, so that robust H optimal stability is guaranteed. Furthermore, for the decoupled equiva...

Batch and continuous systems are of multivariable in nature. A multivariable system is one in which one input not only affects its own outputs but also one or more other outputs in the plant. Multivariable processes are difficult to control due to the presence of the interactions. Increase in complexity and interactions between inputs and outputs yield degraded process behavior. Such processes ...

In this paper, we propose a multivariable Model Driven (MD)-PID control system which is composed of MDPID control systems with PD feedback and inverted decoupling, discuss properties of the control system and also introduce a simple continuous system modeling by using CMA-ES and SIMULINK model, numerical example of a TITO process shows the practically effectiveness.
