摘要

介绍了一种基于神经网络的二自由度微机械臂位置控制方法。该微机械臂由一个由光敏微结构玻璃制成的并联机构和两个压电致动器组成,分别在50x50微米的工作平面上驱动x和y两个自由度。针对微机械臂的磁滞效应严重影响其控制性能的问题,提出了一种基于神经网络的位置控制方法来改善其控制性能。在Matlab/Simulink中建立了微机械臂的仿真模型并提出了基于神经网络的控制算法。

Neural network based control of micro-manipulator
This paper describes a neural network based control approach for position control of a 2DOF micro-manipulator. This micro-manipulator consists of a parallel mechanism, which is fabricated from photo-sensitive micro-structured glass and two piezoelectric actuators (PEA), which actuate the "x" and "y" degrees of freedom on a working plane with dimensions of 50x50 micrometers. Because the control performance of a micro-manipulator severely deteriorates due to the hysteresis effect of PEAs, a neural network (NN) based position control is proposed in this study to improve control performance. A simulation model of the micro-manipulator and proposed neural network based control algorithm have been developed in Matlab/Simulink.
