摘要
为了提高杆驱工业机械臂双液压缸同步控制精度,设计了一种RBF优化模糊PID控制方法,并在Simulink平台完成性能仿真。研究结果表明:速度信号发生了先加速,之后进入稳定速度,最后再减速。低速下,以RBF优化模糊PID控制的双液压缸最大同步误差约为0.08 mm,稳定状态下的误差约为0.01 mm;高速下,以RBF优化模糊PID控制的双液压缸最大同步误差降低至0.11 mm,在稳定状态下的误差减小为0.02 mm。该研究有助于提供工业机器人控制精度,提高双臂协作效率。
In order to improve the synchronization control accuracy of two cylinders of industrial robot arm driven by connecting rod,an improved RBF/fuzzy PID control scheme was designed,and the simulation test was completed by Simulink.The results show that the speed signal first accelerates,then stabilizes,and finally decelerates.At low speed,the maximum synchronization error of the two cylinders with the improved RBF/fuzzy PID control is only 0.08mm,and the error is 0.0022 mm in the stable state.At high speed,the maximum synchronization error of the two cylinders is reduced to 0.11mm with the improved RBF/fuzzy PID control,and the error is reduced to 0.02mm in the stable state.
