摘要: 多机械臂执行协同任务时,由于作业环境、装配条件、系统扰动等诸多非线性因素影响,其末端位置难以精确跟踪目标并保证一致,导致协同工作时产生较大误差。为解决多机械臂位置协同控制问题,通过研究新颖的信任机制,包括信任值(自信任值和互信任值)自适应更新机制和Fisher信息权重(协方差)更新机制,提出一种基于多智能体的自适应位置协调控制算法,当系统存在干扰时,实现多机械臂末端位置一致跟踪到目标位置,提升自动化协同装配任务的控制精度和执行效率。仿真结果验证了所设计方法的有效性。

Abstract: When a multi-manipulator performs cooperative task, it's end position is difficult to accurately track the target and ensure the consistency influenced by the nonlinear factors such as working environment, assembly condition and system disturbances, resulting in large errors during collaborative work. To solve multi-manipulators position coordinated control problem, a multi-agent based adaptive position coordination control algorithm is proposed by researching on the novel trust mechanism, including adaptive update mechanism of trust value (self-trust and mutual-trust) and Fisher information weighted (covariance) update mechanism. In automated collaborative assembly tasks, the precise consensus positioning of end-effector is achieved with improvements in the control accuracy and efficiency. The simulation results verify the effectiveness of the proposed method.

Key words: trust-driven, multi-agent system, adaptive cooperative control, multi-manipulator coordination
