Speeds control of the multi-machines system (MMS) takes a great interest of the scientists in the relevant industry, the real time industrial control systems usually are multidimensional structure, according to the artificial intelligent many researches on the industrial control was carried. The aim of this work is to develop a novel fuzzy logic controller called multi-input multi-output fuzzy logic controller (MIMO-FLC) affect on a winding-unwinding system (Rolling-Unrolling) forming MMS process. This paper introduces a MIMO-FLC applied on speeds regulation of the triple drive paper system, to deal with multivariable control processes, MMS is a non-linear, time varying multi-input multi-output system whose states generally vary with operating conditions, for these reasons control requires a multivariable controller, in our case it is a multivariable fuzzy logic controller. Simulations were approved on MATLAB-SIMULINK environment and show clearly the robustness and the capability of the MIMO-FLC to ensure the system stability improvement with no over tracking and no steady state error with perfected rising time. The results confirm that multi-machines system speeds control process is best achieved using the proposed multivariable fuzzy logic controller.
