Research on the stability of the semi-trailer based on neural network control

It applies the HSRI tire model to set up a two degree of nonlinear dynamic model of semi-trailer. Taking the yaw velocity of tractor as control variables, it proposes the control scheme, develops a controller of BP Neural Network for the semi-trailer stability. Based on the established nonlinear dynamic model, it describes simulation in Matlab/Simulink software platform. The simulation result shows that the method can improve the handling and stability performance on big slip angle for semi-trailer with the controller of NNC(Neural Network Controller).
