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 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=λ−1(p)[yk+pr−yk−Kxk+ŷk]; and applying a control force to the train based on the control force uk. The disclosure may have features of strong adaptability and easy calculation, and achieve high-precision tracking of train speed.
