Observer-based feedback control of interval-valued fuzzy singular system with time-varying delay and stochastic faults

There are countless applications of non-linear systems that incorporate delay and algebraic equations. Despite current improvements in control theory, stochastic actuator defects still pose challenges when it comes to these systems. Furthermore, is not possible measure the states system, uncertainties affect system under investigation, problem becomes even more complex. This paper concerned with fault-tolerant observer-based controller synthesis for delayed singular failures. On basis interval valued models, a new Lyapunov-Krasovskii functional built develop less conservative criterion ensure closed-loop admissible mean-square sense. In addition, as matrices coupled multiple variables, finding parametric observer terms obtained condition complex challenging. The proposed method employs matrix inequality decoupling technique resolve this issue. Eventually, simulations carried out demonstrate applicability method.
