Summary: This article investigates the positive L-1 filter design for positive nonlinear stochastic switching systems subject to phase-type semi-Markov jump process.

Summary: This paper investigates the fault detection issue for complex stochastic delayed systems with positivity constraints and semi-Markov switching parameters. By designing a mode-dependent fault detection filter (FDF), the sensitivity and robustness of the FDF are emphasized to minimize the error between residual and fault signals. Stochastic stability is proposed using a linear copositive Lyapunov functional (LCLF) to satisfy an expected ${L}_{1}$ -gain performance, and solvability conditions for the FDF are established through a linear programming approach. An application example of a data communication network model is provided to demonstrate the effectiveness of the theoretical findings.

Summary: This study investigates the simultaneous reconstruction of sensor fault and actuator fault, as well as fault-tolerant control for nonlinear systems approximated by T-S fuzzy model. By treating sensor fault as part of the state and synthesizing a proportional-integral observer, the reconstructions of sensor and actuator faults are achieved simultaneously. Stability criteria are formulated using linear matrix inequalities, with an FTC scheme provided to maintain system stability in the event of faults. The theoretical results are validated through two real dynamic systems.

Summary: This article addresses the design of nonlinear distributed control laws for continuous-time networked nonlinear heterogeneous systems with bounded sector nonlinear interconnections. New sufficient conditions are derived in terms of linear matrix inequalities, taking into account state constraints and actuators saturation, which can reduce conservatism over decentralized and linear distributed control laws derived following the same method.
