Probability-Dependent Sliding Mode Control Against Sensor Deception Attacks
摘要
In this chapter, the cyber attacks in a fading sensor-to-controller (S/C) channel are considered. Specifically, the multiplicative fading model is introduced to describe the fading phenomenon in the unpredictable communication network, and the channel coefficients are mutually independent random variables that take values in certain intervals. Besides, the randomly occurring deception attacks (RODAs) are modeled by introducing a random process. Under the effect of channel fading and deception attacks, a sliding surface is constructed dependent on the fading probability, and a security finite-time SMC law is proposed to enable the specified sliding surface to be arrived within the given finite time interval. Furthermore, by adopting the partition strategy, sufficient conditions are derived for the stochastic finite-time boundedness (SFTB) over the reaching phase and sliding phase. Finally, under the fading communication and malicious attacks, the developed finite-time SMC approach is verified by an example.
