摘要:

本文研究了多异质机械臂(含冗余和非冗余机械臂)对时变领导者在任务空间中的协调跟踪问题。不同于传统协调控制,本文开发了分布式控制器-估计器算法(DCEA),包含局部算法和网络化算法,用于处理参数不确定性和输入扰动。通过调用微分包含、非光滑分析和输入到状态稳定性,推导了任务空间跟踪误差和子任务误差渐近稳定的条件(包括充分条件和必要充分条件)。仿真结果展示了所提DCEA的有效性。

英文摘要:

This paper studies the task-space coordinated tracking of a time-varying leader for multiple heterogeneous manipulators (MHMs), containing redundant manipulators and nonredundant ones. Different from the traditional coordinated control, distributed controller-estimator algorithms (DCEA), which consist of local algorithms and networked algorithms, are developed for MHMs with parametric uncertainties and input disturbances. By invoking differential inclusions, nonsmooth analysis, and input-to-state stability, some conditions (including sufficient conditions, necessary and sufficient conditions) on the asymptotic stability of the task-space tracking errors and the subtask errors are developed. Simulation results are given to show the effectiveness of the presented DCEA.
