Abstract
A new design method internal model control is proposed for multivariable over-actuated processes that are often encountered in complicated industrial processes. Due to the matrix that is adopted to describe over-actuated system is not square, many classical multivariable control methods can be hardly applied in such system. In this paper, based on method of virtual outputs, a new internal model control method is proposed. The proposed method is applied to shell standard control problem (3 inputs and 2 outputs). The simulation results show that the robust controller can keep the set inputs without overshoot, steady state error, input tracking performance and disturbance rejection performance, the results are satisfactory have proved the effectiveness and reliability of the proposed method.

A New Internal Model Control Method for multi-input and multi-outputs (MIMO) Over-Actuated SystemsUniversity of Tuins El Manar, National Engineering School of Tunis, Laboratory of research in Automatic Control, BP 37, Belvédère, 1002 Tunis, Tunisia
The multi-input and multi-outputs (MIMO) over-actuated systems exist in industrial and such are a difficult problem in the control [12], [21]
For the multivariable system with the number of inputs is superior to that of outputs are habitually met in system industries, we proposed a new method of virtual outputs based on internal model control for over-actuated system has been presented in this paper
