Abstract

• system identification method based on hysteresis loop bias relay feedback without using excitation is designed • hysteresis loop bias relay instead of a controller is proposed • a parameter scheme for the hysteresis loop bias relay to guide the selection of parameters is proposed This paper proposes a closed-loop system identification method based on hysteresis loop bias relay feedback without using excitation. The method utilizes hysteresis loop bias relay instead of a controller to ensure the informativity of data without external excitation and with only noisy feedback. Additionally, this paper proposes a parameter scheme for the hysteresis loop bias relay to guide the selection of parameters more rationally, thus improving the accuracy of the identification model. Compared to recently proposed switching controller methods, the advantage of this method lies in the fact that it requires fewer samples and shortens data collection time. The method's effectiveness is verified through simulation comparisons with typical methods. [ABSTRACT FROM AUTHOR]
