Abstract:
This paper present optimal robust control with different controllers design used in the industrial (didactic or process) system. We designed a controller base on Smith’s predicator controller and Fractional order PID (PI^λD^μ) controller and H_∞ controller. These control techniques has been used with different controller’s types to ensure an optimum control in term of dynamic and static performances of a complex didactic industrial process in accordance with the required specifications. We have described in more details the process, the mathematical model, the structure of FOPID controller and the approximation method (singularity function method of Charef) used to approximate fractional order. The principle of control is decried as well with the different types of controllers used in this study. Finally several simulation and real results are presented which have proved the efficiency of this new control design in term of: stability, robustness and precision.
