The application with a discontinuously variable parameter (moment of inertia) discussed in this paper is represented by an experimental setup, namely the Model 220 Industrial Plant Emulator (M220IPE), which allows the testing of several control solutions by performing real-time experiments. This paper suggests a simple state feedback control structure with three position controllers developed with the aid of linearized mathematical models and particular features of the process. The control structures contain conventional controllers (pid) and also advanced control solutions (Takagi-Sugeno PD+I fuzzy and two-degree-offreedompidcontrollers). The aim of these control structures is to achieve good robustness, good disturbance control behaviours regarding the model uncertainties and also to improve set-point responses. The proposed control structures are validated by digital and experimental results obtained for three specific values of the moment of inertia.

Robust pid controller design methods are proposed for linear single-input single output systems. Non-parametric models represented by a finite number of frequency responses are used for them. Sufficient conditions for closed-loop stability are derived based on the Nyquist stability criterion and the sufficient conditions are reduced to convex constraints. Together with the convex constraints and closed-loop model matching problems the robust pid controller design problems are formulated as convex optimization problems. A important feature of the proposed design methods is that they can be applied to delay-free and time-delay systems in the same manner. Moreover, the proposed methods are extended to two-degree-of-freedompid controller design methods. (C) 2018, IFAC (International Federation of Automatic Control) Hosting by Elsevier Ltd.
