Abstract

Diffeomorphism Transformation Based Disturbance Rejection Control and Its Allocation of Vehicle Dynamic Stable Systems

Highlights

  • Nowadays, as the necessary means of transport for people going out, car driving has brought a series of security problems

  • Most modern passenger vehicles are equipped with active safety systems, including antilock braking system (ABS), traction control system (TCS), direct yaw moment control (DYC) and electronic stability control (ESC)

  • The optimal control allocation of tire force carried out is based on the stability of the vehicle, so we considered that the tire side angle is small enough

Summary

INTRODUCTION

As the necessary means of transport for people going out, car driving has brought a series of security problems. A combination of feedback linearization and disturbance observer-based control (DOBC) is adopted in [18] for the design of a state-feedback controller that regulates the velocity and altitude of air-breathing hypersonic vehicles (AHVs) subject to constrained inputs. We adopt a hierarchical control strategy and a four-wheel drive vehicle model. A vehicle-stabilizing algorithm is presented here, combining with low level control allocation of each wheel longitudinal force under constraints, to ensures that the longitudinal velocity, lateral velocity and yaw rate of vehicles are stable under the disturbance of crosswind in high level There two main contributions in this paper.
