DOI: 10.1016/j.conengprac.2021.104731
Abstract: Abstract In this paper, a disturbance-observer-based control strategy is proposed for longitudinal control and lateral control of unmanned ground vehicles. A composite nonlinear extended state observer is put forward to estimate the total disturbance. A…
