This work studies the stabilization of a class of control systems that use communication networks as signal transmission medium. The lateral motion of independently actuated four-wheel vehicle is modeled as an uncertain-linear system. Time delay and quantization density are modeled as Markov chains.The networked control systems(NCSs) with plants being lateral motion are first transformed to switched linear systems with uncertain parameters. Sufficient and necessary conditions for the stochastic stability of closed-loop networked control systems are then established. By solving the matrix inequalities, this work presents an output-feedback controller that depends on the modes of time delay and quantization density. The controller performance is illustrated via a vehicular lateral motion system. 展开更多

Per-and polyfluoroalkyl substances(PFAS),colloquially known as“forever chemicals,”have emerged as a significant environmental and public health concern due to their extraordinary chemical stability and bioaccumulative nature.1 PFAS exposure is linked to a range of adverse health outcomes,including developmental delays in children,elevated cholesterol levels,immune system impairments,and various cancers. 展开更多
