    Optimal Asynchronous Guaranteed Cost Control of Uncertain Markov Jump Systems With Actuator Saturation and Nonideal Transition Probabilities by Jiazheng Liu, Yang Yang, Yaru Song

    Published 2025-01-01
    “…Third, a convex hull representation is adopted to deal with saturated inputs and parameter uncertainties are incorporated in the system model. Moreover, since it is complex to obtain accurate transition probabilities for the Markov chain of the original system and the hidden Markov model in the observation process, unknown and uncertain transition probabilities are simultaneously considered in both mode transitions and mode observation processes, and a separation strategy is implemented to handle the nonideal probabilities in each process independently. …”
