Optimal H∞ Control for Electromagnetic Suspension Systems with Finite Frequency Specifications

摘要：

　　In this paper,the problem of H∞ control for electromagnetic suspension(EMS)systems is addressed,and cases of both finite and entire frequency are discussed.Firstly a linear state-space model is applied to approximated the complex EMS system,and then H∞ performance index is adopted to measure ride comfort in circumstance of more general exogenous disturbances.By using the generalized Kalman-Yakubovich-Popov(KYP)lemma,the entire frequency H∞ norm is extended to finite frequency case.Consequently,for concerned frequency range,the H∞ performance of EMS system can be further improved.Finally,numerical simulation on an EMS system is performed to validate the effectiveness of the proposed approach.
