本文针对机器人轨迹跟踪控制精度和初始峰值问题,提出一种变增益自抗扰控制器轨迹跟踪控制方法.首先,采用跟踪微分器将逆运动学解处理为插值点区间,设定插值点选取规则及冲击力目标函数.然后,根据目标函数选取插值点拟合得到的轨迹曲线.最后,在考虑机器人动力学下设计轨迹跟踪控制器.仿真和实验结果表明,优化的方法冲击力减少39.8%,且电机能量消耗降低28.48%.设计的变增益自抗扰控制器轨迹跟踪控制可以准确地跟踪轨迹以及解决峰值问题.
Aiming at the problem of robot trajectory tracking control accuracy and initial peak value
this paper proposes a variable gain active disturbance rejection controller trajectory tracking control method. First
the tracking differentiator is used to process the inverse kinematics solution into an interpolation point interval
set interpolation point selection rule and impact force objective function. Then
according to the objective function
the interpolation points are selected to fit the obtained trajectory curve. Finally
the trajectory tracking controller is designed considering the robot dynamics. Simulation and experimental results show that the optimized method reduces the impact force by 39.8%
and the energy consumption of the motor is reduced by 28.48%. The designed variable gain active disturbance rejection controller trajectory tracking control can accurately track the trajectory and solve the peak problem.
