为了提升机械臂工作的效率,提出了一种基于混合粒子群算法的轨迹规划优化方法,使用 5 次 NURBS 曲线为工作轨
迹,利用混合粒子群算法,针对机械臂的脉动冲击、能量消耗和工作时间 3 个目标建立目标函数并获得帕累托最优解集,将权重
目标函数归一化从而得到期望解。 在 MATLAB 环境下由这一方法建立模型进行仿真,并选取六轴机械臂进行仿真分析之后得
出非支配解集,并选取最优解,证实了该轨迹规划方法可以有效的提升机械臂的运行效率,并且能够实现约束条件下的多目标
优化。 |
英文摘要: |
In order to promote the work efficiency, energy consumption and the smoothness of the manipulator, a mathematical model of
quantic non uniform rational B-spline curve (NURBS) was set up to find trajectory with high-order of which endpoint parameters was
specified. A hybrid particle swarm optimization algorithm ( HPSO) was used in the MATLAB simulation to get the perfect Pareto
solutions under three normalized weighted objectives for six-degree freedom manipulator’ s trajectory. Through the simulation, it shows
that the quantic NURBS curve can be constructed to fitting high order trajectory and the HPSO algorithm can provide a good means to get
the Pareto solutions for the trajectory described above. |
