| Abstract: |
| Actuator faults usually cause security problem in practice. This paper is concerned with the security control of positive
semi-Markovian jump systems with actuator faults. The considered systems are with mode transition-dependent sojourntime
distributions, which may also lead to actuator faults. First, the time-varying and bounded transition rate that satisfies
the mode transition-dependent sojourn-time distribution is considered. Then, a stochastic co-positive Lyapunov function is
constructed. Using matrix decomposition technique, a set of state-feedback controllers for positive semi-Markovian jump
systems with actuator faults are designed in terms of linear programming. Under the designed controllers, stochastic stabilization
of the systems with actuator faults are achieved and the security of the systems can be guaranteed. Furthermore, the
proposed results are extended to positive semi-Markovian jump systems with interval and polytopic uncertainties. By virtue
of a segmentation technique of the transition rates, a less conservative security control design is also proposed. Finally,
numerical examples are provided to demonstrate the validity of the presented results. |
