报告内容摘要:
Recently, Steer-by-Wire (SBW) systems have been developed in road vehicles to replace the current electric power and hydraulic power-assisted steering systems, owing to the relaxed installation constraints, reduced power consumption and enhanced vehicle stability and safety. Due to the fact that large system parameter uncertainties and tyre self-aligning torque are involved in the SBW systems, robust steering controllers should be carefully designed to achieve excellent steering performance for different driving environment and road conditions.
In this talk, our recent work of developing a novel adaptive terminal sliding mode (ATSM) control scheme for an SBW vehicle will be presented. It will be shown that the developed ATSM controller can drive the closed-loop error dynamics to converge to zero in a finite time, where adaptive laws are applied to estimate the uncertain bounds of the system parameters and disturbances in Lyapunov sense. Compared with the sliding mode-based SBW control systems, the proposed ATSM control not only assures the finite-time error convergence and strong robustness with respect to parameter uncertainties and varying driving conditions, but requires no prior knowledge of the system parameters and road information. Experimental results from an SBW vehicle will be demonstrated to verify the remarkable performance of the proposed control in terms of the robustness, error convergence and road disturbance attenuation, in comparison with other control strategies.
