摘要: In this paper, we investigate an H∞ miscellaneous information feedback controller (HMIFC) for active suspension system stabilization. An auxiliary signal is introduced in the control channel via a wireless communication network. Under scheme, onboard measured and network transmission are simultaneously used to improve performance. To handle impact of network-induced delays, delay-dependent stability criterion closed-loop derived based on Lyapunov theory linear matrix inequality (LMI) method. By considering augmented Lyapunov–Krasovskii functional (LKF) relaxed integral inequality, new existence condition can be obtained. Compared with traditional controller, designed acquire better ride comfort subject same constraints. Finally, comparative simulation experimental results prove effectiveness presented controller.
