Dual-rate Sampled-Data H∞ Control for Vehicle Active Suspension Systems

摘要：

　　This paper investigates the problem of dual-rate sampled-data H∞ control for a vehicle active suspension system.In the system,the state variables are sampled by two types of sensors,and the ratio of two sampling rates is assumed to be a positive integer.Depending on whether the sampled states at two sampling rates are available simultaneously or separately,a periodic switched controller is proposed.Then,by using an input delay approach,the closed-loop system is modeled as a switched system with different input delays.A delay-dependent criterion on the existence of the switched controller is established such that the system is exponentially stable with a prescribed H∞ performance.The effectiveness of the proposed method is shown by a numerical example.
