连续性电液伺服系统位移轨迹的滑模跟踪控制
Sliding mode tracking control of displacement trajectory of continuous electro-hydraulic servo system
摘要
Abstract
This paper disscusses the efforts to address the displacement trajectory chattering of track-ing piston rod when electro-hydraulic servo system moves near zero position and proposes an improved continuous electro-hydraulic servo model.The study involves designing a switching hyperplane and a reaching law using sliding mode control method;establishing a sliding mode tracking controller of the e-lectro-hydraulic servo system under the same atmospheric pressure;simulating to analyzing the continuous electro-hydraulic servo system and the traditional electro-hydraulic servo system;and analyzing the track-ing and control precision of the displacement trajectory of the electro-hydraulic servo system.The results show that,compared with traditional electro-hydraulic servo system,the continuous electro-hydraulic ser-vo system smooths the buffeting phenomenon of 2 kHz with the displacement trajectory tracking of the pis-ton rod,and the tracking accuracy of displacement increases by 5%.关键词
