基于分数阶模型的磁流变阻尼器振动系统的预测控制
Predictive control of vibration system of magnetorheological damper based on fractional order model
摘要
Abstract
Because of the controllable damping characteristics,magnetorheological damper can be used to produce high-quality shock absorber.In recent years,it has been developed in the field of industrial vibration control by com-bining design with variety of control strategies.Researches show that the fractional model has high accuracy of fitting to the MR damper.In this paper,the viscoelastic properties of the MR damper are described by the fractional model, and the approximate fractional transfer function is obtained by the Oustaloup approximation method.A new model predictive controller is designed based on the quadratic performance index of the output tracking input after the dis-cretization.Finally,the simulation results show that the predictive controller has good dynamic performance and verify the feasibility and stability of the design.关键词
