Improved relay feedback identification using shifting method
Original language description
This paper presents a new method for estimation of a static gain and remaining parameters of a second order time delayed model by relay feedback identification. For this purpose, it uses a recently published method called shifting method which enables to estimate two points of frequency characteristic from a single relay feedback test. These two frequency response points are determined without any assumptions about a model transfer function and they can be used for fitting parameters of a process transfer function with various structures. For the first time the shifting method is used for a static gain estimation. This unique solution is even applicable under constant load disturbance. A great advantage for practical use is the comprehensibility and computational simplicity of the method. This identification method is primarily proposed for automatic tuning of controllers. The method is demonstrated on a simulated example and a laboratory apparatus “Air Aggregate”.
