| 中文摘要 |
| 针对参数不确定双臂柔性机械手系统, 提出一种基于遗传算法的终端滑模控制方法, 以实现其末端控制.基于输出重定义方法, 通过输入输出线性化, 将系统分解为输入输出子系统和内部子系统. 设计终端滑模控制策略,使输入输出子系统有限时间内收敛到零, 内部子系统变为零动态子系统; 采用遗传算法优化零动态子系统参数, 使其在平衡点附近渐近稳定. 根据Lyapunov稳定性理论算出末端输出位移的误差范围. 仿真结果证明该方法有效性. |
| 英文摘要 |
| A terminal sliding mode control method based on genetic algorithm is proposed for the end-tip control of twolink flexible manipulators with uncertain parameters. The output of the manipulator system is redefined. By input-output linearization, the system is decomposed into an input-output subsystem and an internal subsystem. A terminal sliding mode control strategy is designed to make the input-output subsystem converge to zero in finite time. The internal subsystem is converted into a zero dynamic subsystem. A genetic algorithm is adopted to optimize the parameters of the zero dynamic subsystem to guarantee its asymptotical convergence to the neighborhood of the equilibrium point. The error range of end-tip output is calculated by Lyapunov stability theorem. Simulation results are presented to validate the design. |
