Shifting Method for Relay Feedback Identification and Control of Delayed Systems
Original language description
The paper deals with identification and control of time delay stable plants. A single relay feedback test and the new method called “shifting method” are used for plant identification. For this purpose an asymmetric relay is used. This approach enables to estimate three points on a plant frequency response for three important frequencies from sustained oscillations obtained by a single relay test without using the FFT algorithm. This technique extends possibilities of relay feedback identification and allows fitting up to five parameters of plant transfer functions. This identification method is used for estimating five parameters of the selected anisochronic model that is very universal and convenient for modelling time delay stable systems. This model is then used for anisochronic controller design. The anisochronic controller is proposed by the Desired Model Method. The shifting method and the anisochronic controller design are demonstrated on one simulation example and on the laboratory apparatus called “Air Aggregate”. These experiments were performed using Matlab/Simulink programing environment. The introduced approach provides an automatic tuning tool for a large class of common control problems.
