摘要:
为了降低抓持力控制偏差,从而避免机器人柔顺抓取系统在采摘过程中损伤月季花梗,在传统阻抗控制基础上引入环境参数估计实现柔顺抓持力控制。通过梯度下降法在线估计弯曲刚度并修正参考位置以降低抓持力稳态误差。在MATLAB/Simulink中进行抓取系统仿真。结果表明:所使用的改进阻抗控制算法相对于传统阻抗控制算法能有效减小稳态误差,11个不同刚度参数花梗的抓持力上升时间都在0.42 s以内、超调量在20%以内。最后,实验验证了系统能实现低稳态误差的抓持力控制,能满足月季采摘的要求。
Abstract:
To reduce the deviation of grasping force control so as to prevent the compliant grasping system of robot from damaging the China rose stems during the picking process, environmental parameters estimation was introduced on the basis of traditional impedance control to achieve compliant grasping force control. The bending stiffness was estimated online by the gradient descent method and the reference position was corrected to reduce the steady-state error of the grasping force. The grasping system simulation was carried out in MATLAB/Simulink. The results show that the improved impedance control algorithm can effectively reduce the steady-state error compared with the traditional impedance control algorithm. The rising time of the grasping force of 11 stems with different bending stiffness is within 0.42 second, and the overshoot is within 20%. Finally, experiment proved that the system can realize the grasping force control with low steady-state error, which can meet the requirements of China rose picking.
