The Optimal Control of Tractor-semitrailer Steering Stability
摘要
Abstract
The optimal controller of direct yaw-moment control of tractor-semitrailer was designed, and its effective- ness was verified. The Gim tire model was adopted to set up the nonlinear dynamic model of tractor-semitrailer. Choosing slip angle of tractor, yaw velocity of tractor and semitrailer, and angle of central line of tractor and semi- trailer as control variables, the optimal control scheme was proposed. An optimal controller of direct yaw-moment control for the tractor-semitrailer stability was developed based on model tracing control technique. Based on the es- tablished nonlinear dynamics model, simulation in Matlab/Simulink software environment is described. The simula- tion consults suggest that for tractor-semitrailer with optimal controller of DYC, the handling and stability perform- ance on big slip angle can be improved, which makes the driver drive the vehicle normally.关键词
