Passive analysis and finite-time anti-disturbance control for semi-Markovian jump fuzzy systems with saturation and uncertainty
作者：
Highlights：
• Due to the effect of complex working environment, we consider the uncertain parameters, multiple disturbances, time delay, generally uncertain TR, actuator saturation and nonlinear in a unify S-MJFSs.
• The sufficient conditions of finite-time boundedness for S-MJFSs rely on the analysis of Lyapunov-Krasovskii functional.
• The design method of finite-time passive controller is obtained for S-MJFSs.
• DOBC method is used to suppress external disturbance to achieve the performance of S-MJFSs.
• The finite-time performance of S-MJFSs based on uncertainty and saturated nonlinearity is proposed.
• Additionally, representing a single-link robot arm model as S-MJFSs illustrates the effectiveness of the controller design algorithms.
