Abstract

Time delay compensation is one of the crucial issues in real-time hybrid tests of hunting mitigation of high-speed trains. Since multiple natural frequencies of high-speed trains exceed 10 Hz, the load command inevitably contains high-frequency components, which in turn necessitates a smaller time delay errors to ensure test stability. To address this problem, based on the fundamental idea of the two-stage adaptive time delay compensation method, an inverse model of the loading system is utilized to compensate for the nominal time delay, and a finite impulse response discrete model is applied to establish an adaptive inverse controller for the residual time delay and uncertainty time delay, whose parameters are online estimated by the fading-memory Kalman filter. For fully exploring the performance of the proposed method, virtual real-time hybrid tests of high-speed train with linear and nonlinear specimen-loading-system models were conducted. Performance of different time delay compensation methods was compared. The study showed that the proposed method has excellent compensation performance, and exhibits stronger robustness and good ability to compensate for high-frequency signals.
