| description | ObjectiveIn order to realize the precise control of a certain type of electro-hydraulic position servo system, a feedback-feedforward variable gain iterative learning method is proposed. MethodFirst, the simplified model of the electro-hydraulic position servo system is established, then the iterative learning control algorithm is improved and a variable gain learning law with a forgetting factor is adopted. Finally, Matlab simulation is carried out for verification. ResultsThe simulation results show that compared with traditional iterative learning and PID control, the improved iterative learning algorithm has better convergence and smaller tracking error, and can make the electro-hydraulic position servo system track the position curve quickly and accurately with improved dynamic characteristics.ConclusionThe results of this paper can provide references for the control performance optimization and practical engineering application of electro-hydraulic position servo systems. |
