针对移动机器人在高性能输出和长时间续航等方面的综合工作性能需求,提出一种针对机器人关节的多性能同步优化端口受控哈密顿能量控制方法.首先,建立机器人关节的数学模型和哈密顿能量控制模型,并推导出能方便采用模型代理优化算法的关节靶向能量传输系统模型;其次,搭建能量闭环控制器,与磁场矢量控制结合完成机器人关节的控制闭环,并设计了多性能同步优化控制策略使得机器人关节在保证运行输出能力的同时获得最长的续航能力.MATLAB/Simulink仿真结果表明,多性能同步优化端口受控哈密顿能量控制器使机器人关节拥有较好的输出稳定性,同步优化控制策略在与其他控制策略的输出能力和续航能力等多指标的综合对比分析中展现了优势.
Research on Joint Multi-Performance Synchronization Optimization Control for Robots Based on Energy Control and Agent Optimization Algorithms
In order to address the comprehensive performance requirements of mobile robots,such as high performance output and long-term endurance,a joint multi-performance synchronization optimization port-controlled Hamiltonian energy control method is proposed.Firstly,the mathematical model of the robot joint and the Hamiltonian energy control model are established,and the joint-targeted energy transmission system model,which can be conveniently optimized using model-based optimization algorithms,is derived.Second-ly,an energy closed-loop controller is constructed,which,combined with the magnetic field vector control,achieves closed-loop control of the robot joint.A multi-performance synchronization optimization control strategy is designed to ensure both the operational output capability and the longest endurance of the robot joint.MATLAB/Simulink simulation results demonstrate that the joint multi-performance synchronization optimization port-controlled Hamiltonian energy controller provides good stability for the robot joint,and the synchronization optimization control strategy exhibits advantages in terms of output capability and en-durance compared with other control strategies through comprehensive multi-criteria analysis.
