基于力失衡的二维主动磁悬浮驱动方法分析与测试
Analysis and Test of Two-Dimensional Active Maglev Actuation and Control Method Based on Force Imbalance
摘要
Abstract
A magnetic levitation actuation system based on force imbalance is proposed,and a neural network PID(Proportion Integration Differentiation)control method is designed to activate actuation of external magnetic field,which can effectively deal with the complex actuation system with nonlinear and unclear model parameters.Experimental results show that the proposed control algorithm solves the problems such as the increase of deviation between the controlled object and the steady-state operating point and the rapid dete-rioration of tracking performance in the model-based control method.The stable levitation and high-precision controllable motion of the magnetic ball in two-dimensional space is realized.It can be applied to the non-destructive quality detection of the inner wall and the internal dredging of the long and thin pipeline in the industrial field,and the examination and operation of the blood vessel and intestinal cavity in the medical field.关键词
