Fuzzy Direct Yaw- moment Control of Four- wheel Steering Tractor- semitrailer
摘要
Abstract
The Gim tire model was adopted to set up the nonlinear dynamic four - wheel steering dynamic model of tractor - semitrailer. A four -wheel steering with direct yaw - moment control scheme was proposed. Choosing yaw velocity of tractor as control variables, the fuzzy controlscheme was proposed. A fuzzy controller of DYC for the tractor - semitrailer stability was developed. Simulation on a slip angle minimization four -wheel steering tractor - semitrailer in Matlab/Sim-ulink is described. The simulation consults suggest that for four - wheel steering tractor - semitrailer with direct yaw - moment control,a good response can be achieved, which makes the handling and stability performance on big slip angle improved,and makes the driver drive the vehicle normally.关键词
