Dynamic Event‐Triggered‐Based Finite‐Time Control for Vehicle Suspension Systems With Imperfect Communication Channels

ABSTRACT Within the framework of privacy protection, this paper explores the issue of finite‐time dynamic event‐triggered fuzzy control for vehicle suspension systems (VSSs) with imperfect communication channels. Firstly, a privacy protection mechanism is introduced into the VSSs to protect the privacy of data, which avoids data being accessed or misused without authorization, thereby enhancing the safety of the driving experience. Secondly, under the privacy protection mechanism, a novel dynamic event‐triggered mechanism (DETM) is proposed for VSSs. Compared to existing DETMs, the designed DETM not only adjusts the threshold based on real‐time environmental changes and achieves better system performance while reducing data transmissions but also reduces the risk of data leakage during transmission. Then, a finite‐time state encrypted fuzzy controller subject to imperfect communication channels is designed, which ensures that the closed‐loop system is finite‐time bounded. Simultaneously, the requirements for the VSSs are also met. Finally, a simulation example is provided to illustrate the effectiveness of the designed control approach.
