Abstract

An nonlinear observer-based longitudinal control law for vehicles is presented in this paper. It is assumed that for vehicle i knows only the distance between vehicle i and the preceding vehicle, i-1. An nonlinear state observer for vehicle I is developed to estimate the velocity and acceleration of the preceding vehicle, i-1. The communication of the position, velocity, and acceleration information is not used in the proposed method. It will be shown by mathematical analysis that the longitudinal control of vehicle can be implemented without an communication of the informations. It will be proven that the observation errors of the nonlinear states converge to zero asymptotically. To show the effectiveness of the proposed method, the simulation results are presented for the longitudinal control of the vehicle.

본 논문에서는 차량의 추종 주행 제어기를 비선형 상태관측자를 이용하여 설계한다. i 번째 차량(추종차량}과 i-1 번째 차량(선행차량) 간의 거리(상대거리)만을 측정하여 아는 것으로 간주 한다. 선행차량의 속도 및 가속도를 추정하기 위한 비션형 상태관측자를 설계하여 추종차량의 추종 주행 제어기에 이용할 수 있도록 한다. 본 논문에서 제안하는 방법이 차간 통신이 필요 없음을 수학적으로 증명한다. 또한 비선형 상태관측자를 이용하여 추정한 선행 차량간의 상대속도 및 상대가속도 오차가 '0' 으로 수렴함을 증명한다. 제안한 방법의 타당성은 수학적인 증명과 더불어 컴퓨터 시뮬레이션을 통하여 검증한다.
