基于修正黏性摩擦LuGre模型的比例多路阀摩擦补偿
Friction Compensation of Proportional Multi-way Valve Based on Modified Viscous Friction LuGre Model
摘要
Abstract
To decrease the influences of friction on the proportional multi-way valves,the meth-ods of friction characteristic analysis,parameter identification and friction compensation of propor-tional multi-way valves were proposed based on modified viscous friction LuGre model.The friction data were indirectly obtained through the experimental tests.The static and dynamic parameters of modified viscous friction LuGre model were identified by data fitting.The friction state observer of modified viscous friction LuGre model was designed by use of the identified parameters,and the out-put of state observer was fed back to the input port of control model to reduce the adverse effect of friction on the proportional multi-way valve performances.Simulation results show that the location tracking accuracy of proportional multi-way valves may be improved by using the friction compensa-tion with identification parameter method based on modified viscous friction LuGre model.关键词
