  • Patent number: 12030541
    Abstract: The invention discloses a method and a system for state feedback predictive control of a high-speed train based on a forecast error. The method comprises: obtaining a speed prediction model of a high-speed train y ^ k + p = C ? A p ? x k + ? i = 1 p ? C ? A i - 1 ? B ? u k + p - i ; predicting speeds of the train at times k and k+p according to the speed prediction model; obtaining an actual speed output value of the train; determining a speed prediction error at time k according to the prediction speed of the train and the actual speed output value of the train; correcting a prediction speed of the train at time k+p, according to the speed prediction error, to obtain a corrected prediction speed of the train; calculating a control force uk of the train according to uk=??1(p)[yk+pr?yk?Kxk+?k]; and applying a control force to the train based on the control force uk.
