摘要: 为了解决绳驱冗余机械臂逆运动学求解问题,基于混沌映射和反向学习方法对粒子群算法进行改进,并引入子种群粒子和种群规模动态调整策略,提出一种混沌初始化的动态重组多种群粒子群优化算法(Dynamic Reorganization Multi-swarm Particle Swarm Optimization algorithm,DRMPSO)。建立绳驱冗余机械臂运动学模型,构造以机械臂末端最小位姿误差和最低能量消耗为目标的适应度函数。通过与其他算法对机械臂逆运动学求解问题进行比较,表明所提出的动态重组多种群粒子群优化算法在求解精度和稳定性上均具有明显的优势。最后,将动态重组多种群粒子群优化算法用于机械臂的运动规划中,仿真结果表明,动态重组多种群粒子群优化算法在使机械臂达到末端位置的同时还能保证姿态的连续性,机械臂运动过程流畅。

Abstract: In order to solve the inverse kinematics solving problem of the cable-driven redundant manipulator,the particle swarm algorithm was improved based on the strategies of chaotic mapping and inverse learning,and sub-population particles as well as the dynamic adjustment strategy of the population size were introduced to propose a Dynamic Reorganization Multi-swarm Particle Swarm Optimization (DRMPSO) algorithm with chaotic initialization. The kinematic model of the cable-driven redundant manipulator was established,and the fitness function with the minimum position error and the minimum energy consumption at the end of the manipulator was constructed. By comparing with other algorithms for the inverse kinematics of the manipulator,the proposed dynamic reorganization multi-swarm particle swarm algorithm has obvious advantages in both solution accuracy and stability. Finally,the dynamic reorganization multi-swarm particle swarm algorithm was used in the motion planning of the robotic arm,and the simulation results show that the dynamic reorganization multi-swarm particle swarm algorithm can ensure the continuity of the attitude while the robotic arm reaches the end position,and the robotic arm motion process is smooth.

Key words: cable-driven redundant manipulator, inverse kinematics, particle swarm optimization algorithm, chaotic mapping
