Aircraft Carrier Arresting Buffer Control Algorithm Research Based On Magneto-rheological Technology

The device performance of Aircraft hinder has the vital significance on the performance of the carrier play.Magnetorheological fluid is a new kind of intelligent material which has an excellent response speed and controllability.It is being gradually applied to various fields.Exploring the magnetorheological technology application in aircraft hinder device has a certain practical significance.The modeling of magnetorheological damper,device principle and control method was studied in this article.Firstly,the meaning of this article is explicit based on the statement of the development,application and research situation of arrestment.The mechanics model of arrest process was built by analysis of the force in the arresting process.At the same,recent progress in magnetorheological damper is reviewed.A large size of magnetorheological damper model was built considering the characteristics of magnetorheological damper which did a good job in application of the magnetorheological damper.Secondly,according to the characteristics of the aircraft arresting process and the magnetorheological damper,the sliding mode control method was used to investigate the process of aircraft arresting.The solution of stabilization control is put forward for the chattering phenomenon introduced by the sliding mode controller.The simulation verified the control algorithm and the measures of avoiding vibration.Finally,the conventional PID control could not achieve the ideal control effect because of the complex change of the aircraft arresting force.This article proposed an improvement of PID method to control the process of arresting.The simulation verified the adaptability of algorithm.In addition,this paper compared the two control algorithms in order to get a more comprehensive research conclusion.
