ABSTRACT

 This paper introduces a new simple technique extending possibilities of the relay feedback identification. The technique enables to estimate up to five parameters of the system transfer function without using the FFT algorithm. For this purpose it is used one conventional relay feedback experiment with an asymmetric relay. The suggested technique is used for estimating five parameters of the anisochronic model because this model is very universal and convenient for modeling time delay stable systems. The anisochronic model is then used for anisochronic controller design by the Desired Model Method. The practical applicability of the suggested identification technique and the designed anisochronic control is demonstrated on the physical laboratory model “Air Aggregate”. All experiments were performed using Matlab/Simulink programing environment. The introduced relay feedback identification can be applied even for automatic tuning.
