摘要:

针对发生执行器攻击现象的自主无人车辆(AUV)路径跟踪控制问题,提出一种基于模糊滑模变结构的鲁棒安全控制设计方法。根据AUV的动力学行为建立了基于状态空间的路径跟踪控制模型,利用滑动模态对执行器攻击信号的不变性,设计了一种积分型滑模安全控制策略,通过选取合适的Lyapunov函数,推导出发生执行器攻击情形下AUV路径跟踪控制的稳定性和前轮转角控制增益。进一步,通过结合模糊控制规则设计了可自适应调节的切换项增益,利用MATLAB/Simulink和CarSim联合仿真实验平台验证所提控制策略的有效性。结果表明:相较于执行器攻击下,车速为72 km/h,在单移线和双移线2种工况下,路径跟踪最大误差分别减少5.6%、6.2%,方向盘转角减少73.9%、75.4%,质心侧偏角减少249.9%、213.9%。该控制策略能够增加AUV路径跟踪过程中的鲁棒性,保证良好的路径跟踪性能。

Abstract:

A robust safety control design method based on fuzzy sliding mode variable structure was proposed to solve the path following control problem of autonomous unmanned vehicle (AUV) with actuator attacks. A state-space-based path following control model was established to characterize the dynamic behaviors of AUV. Using the invariance of sliding mode to the actuator attack signal, an integral sliding mode safety control strategy was designed, by selecting appropriate Lyapunov function candidate, the stability of AUV path following control and the gain of front wheel angle control under actuator attacks were derived. The adaptively adjustable switching term gain was designed by combining fuzzy control rules, MATLAB/Simulink and CarSim co-simulation platform were used to verify the effectiveness of the proposed control strategy. The results show that the maximum error of path following is reduced by 5.6% and 6.2%, the steering wheel angle is reduced by 73.9% and 75.4%, and the side slip is reduced by 249.9% and 213.9%, respectively comparing with the case that the vehicle speed is 72 km/h under single and double line-shifting conditions. This control strategy can increase the robustness of AUV path following process and ensure good path following performance.
