Research on Spool Vibration Suppression of Direct Drive Servo Valve Based on ADRC and MPC
摘要
Abstract
Direct drive servo valve gradually expands its application scenarios because of its advantages such as simple structure,strong antipollution ability and large output power.As one of the key components of flight control system,the characteristics and reliability of electro-hydraulic servo valve are directly related to flight performance and safety.In order to solve the problem of spool oscillation of a type of dual-system direct drive servo valve for aviation,a new control method for spool oscillation suppression is proposed in this paper.The component level mathematical model of the direct drive servo valve system is established,and the calculation is combined with the sudden fluid flow force model in the previous study.The composite control method of ADRC and active prediction is designed and compared with the traditional PID control method.The results show that the combined control method of ADRC and active prediction can effectively counteract the influence of sudden fluid flow force on the spool movement of linear motor current,and provide a theoretical reference for the controller design of direct drive servo valve under complex stress environment.关键词
