操作器的PID自适应控制

AN PID ADAPTIVE CONTROL SCHEME FOR ROBOT MANIPULATORS

  • 摘要: 利用操作器动力学模型的性质,提出了一种前馈补偿加PID反馈控制的自适应控制方案.由于在控制力矩中引入积分项,使操作器关节的跟踪精度和抗干扰能力得到提高.本文分析了摩擦干扰和执行机构的惯性对控制方案的影响.本文进一步的研究表明:在许多情况下,只需对操作器动力学中耦合和非线性最强的项进行补偿,然后加PID反馈控制,就能取得较好的控制效果.从而简化了控制方案,以PUMA560的前三个关节的参数作模型,对文中的方法进行了仿真.

     

    Abstract: An adaptive control scheme with feedforward compensation and PID feedback is developed for robotmanipulators to track a desired trajectory. The tracking precision and the ability to overcome disturbance are im-proved due to the integration part in control torque. The effect of friction and inertia of the actuator to the controlscheme is discussed. Further studies indicate that we only need to compensate the strongest interactions and nonlinearities in robotdynamics and then we can achieve a satisfactory control result simply by using PID feedback control. A computersimulator for the PUMA560 robot was given to investigate the performance of the proposed control schemes.
