Abstract: This paper studies the asynchronous double-source bumpless transfer (BT) finite-time secure control issue for stochastic hidden semi-Markovian jump systems (HSMJSs) with Brownian noise. The HSMJS is assumed to suffer from deception attacks governed by Bernoulli variables, which occur randomly in both sensor-controller (SC) and controller-actuator (CA) channels. Firstly, a hidden semi-Markovian model is established to characterize asynchronous jumping between HSMJS and controller modes. Secondly, a novel double-source BT constraint condition is proposed to reduce control bumps caused by asynchronous jumping and deception attacks in the SC channel. Thirdly, asynchronous BT secure controllers are constructed to achieve finite-time secure control for stochastic HSMJSs subject to deception attacks. Finally, a circuit system with asynchronous jumping modes is presented to demonstrate the feasibility and practicality of the proposed approach.
