Synchronous Control of Airbag Ejection Mechanism for Underwater Logging Device

Abstract:

For the characteristics of electro-hydraulic position synchronous control system with long pipelines of the underwater logging device’s airbag ejection mechanism, the mathematic model of the single cylinder subsystem considering pipeline effect is established. On this basis, the tracking controller of subsystem is designed by combining a disturbance observer with a Smith predictor and the tuning method of control parameters is given using ITAE criterion. The fuzzy PI controller is designed based on a composite synchronous control scheme. The simulation results show that the proposed control method has good robust performance and can meet the requirement of high precision synchronous.
