Dear editor,recently, considerable attention has been devoted to output feedback co.trol and practical tracking of nonlinear systems [1, 2]. Unfortunately, limitations of sensor techniques can cause sensitivity errors in practical environments. For example, ref. [3] showed that the displacement sensor of a magnetic bearing suspension system experienced ±10%sensitivity error in practice. Thus, investigating nonlinear systems with unknown measurement sensitivity is valuable.

This paper addresses the problem of robust adaptive co.trol for robotic systems with model uncertainty and input time-varying delay. The Hamiltonian method is applied to develop the stabilization results of the robotic systems. Firstly, with the idea of shaping potential energy and the pre-feedback skill, the n degree-of-freedom(DOF) uncertain robotic systems are realized as an augmented dissipative Hamiltonian formulation with ***, based on the obtained Hamiltonian system formulation and by using of the Lyapunov-Krasovskii(L-K) functional method, an adaptive co.troller is designed to show that the robotic systems can be asymptotically stabilized depending on the input delay. Meanwhile, some sufficient conditions are spelt out to guarantee the rationality and validity of the proposed co.trol law. Finally, study of an illustrative example with simulations shows that the co.troller obtained in this paper works very well in handling uncertainties and input delay in the robotic systems.

利用退役电池构建储能系统,充分利用其剩余价值,是解决大量退役电池再利用的重要途径。然而,经过多次充放电影响,退役电池不一致性问题较新电池更为突出。在此背景下,首先,针对退役电池储能系统提出了分层式可重构均衡拓扑。其次,基于该拓扑提出了分层式均衡控制策略。考虑组内部和组间两个层次的均衡控制,组内以SOC和端电压为均衡变量,通过重构实现电池单体状态均衡,组间以SOC为均衡变量,通过重构保证全电池簇均衡。同时考虑多种运行工况:静置过程中通过自均衡提高电池组的均衡效率和可用容量,放电过程中通过拓扑结构变换维持输出电压稳定,充电过程中考虑能量损耗和充电速度合理优化充电电流,缩短充电时间,减少温升,延长电池使用寿命。最后,在Matlab中验证了所提拓扑与均衡策略在不同工况下的有效性。
