2021年7月14日下午,小型学术研讨会“International Workshop on Intelligent Control of Autonomous Unmanned Systems”在学院1号楼405会议室顺利召开。英国拉夫堡大学Wen-Hua Chen教授、Jun Yang高级讲师和Jingjing Jiang讲师受邀参会,并通过腾讯会议分别做了题为“Dual Control for Exploration and Exploitation”、“A Nonsmooth Nonrecursive Synthesis (NNS) Framework for Nonlinear System Control”和“Shared Control: An Integration of User Control and Automated Entities”的学术报告。研讨会由365best体育官网入口副院长陈谋教授主持,学院三十余位师生现场参会,另外四十余位师生在线参加了本次研讨会。
Chen教授首先对自动搜索的应用背景做了简要介绍,重点指出了自主无人系统在环境保护等背景下自动搜索的研究意义。Chen教授将自动搜索问题考虑为一种新型控制问题,并提出了一种全新的自动探索DCEE(Dual Control for Exploration and Exploitation)框架。DCEE框架能够在没有指定目标位置和搜索路径的未知环境条件下驱动无人系统接近未知源。然后以无人机为例,多组实验结果展示了DCEE的有效性。最后,Chen教授对自主无人系统自动探索的未来研究方向提出了展望。
Jun Yang老师首先简要介绍了高阶非线性系统的研究难点,从而给出了非光滑非递归综合(Nonsmooth Nonrecursive Synthesis,NNS)框架的研究意义。然后为解决递归设计在高阶系统中的控制器形式复杂、参数调节困难等问题,将NNS框架分别结合干扰估计补偿、鲁棒与自适应控制方法,实现高阶非线性系统的抗干扰控制和鲁棒跟踪控制。随后通过仿真对所提出的方法进行了验证。最后,Jun Yang老师对汇报内容进行了总结,并对NNS框架未来的研究方向提出了展望。
Jingjing Jiang老师分享了在共享控制方面的最新研究成果。首先,对共享控制的应用背景和工作原理做了简要介绍。针对受约束的机械系统,设计了共享控制律,使系统在满足约束的同时保证了误差的收敛性。随后,以低速车辆运动学模型为例,对操作员和反馈控制器之间的动态控制进行权重分配,同时保证了系统的全局稳定性。仿真实验表明了所提出的控制方案在机械系统和交通环境中应用的有效性。最后,Jingjing Jiang老师对共享控制的研究前景提出了展望。
报告结束后,Wen-Hua Chen教授、Jun Yang老师和Jingjing Jiang老师分别与参会师生针对报告内容进行了热烈的讨论,并对师生们提出的问题给予了详细的解答。
