[00495] Input-state finite time stabilization of singular Markov fuzzy system.

Session Date & Time : 1C (Aug.21, 13:20-15:00)
Type : Contributed Talk
Abstract : This work aims to examine the problem of Input-state finite-time stabilization of singular Markov T-S fuzzy systems with input time delay and disturbance. The sampled-data control for a singular Markov T-S fuzzy system with the quantized state has been designed. Using Lyapunov stability theory and linear matrix inequalities we guarantee that the singular fuzzy system is Input state Finite time stable. Finally, a numerical example is used to show the effectiveness of the proposed method.

Type : Contributed Talk
Abstract : In this work, the robust repetitive tracking control design problem for Takagi-Sugeno fuzzy model based Markovian jump systems in the presence of disturbances is investigated. Specifically, a new set of adequate conditions is derived in the form of matrix inequalities with the use of Lyapunov technique to obtain the controller gain matrices. In order to verify the effectiveness and supremacy of the proposed control design, the simulation results with numerical examples are presented.

[01539] Actuator fault reconstruction-based tracking control for periodic piecewise polynomial systems

Session Date & Time : 1C (Aug.21, 13:20-15:00)
Type : Contributed Talk
Abstract : The problem of actuator fault reconstruction and fault-tolerant tracking control for periodic piecewise polynomial systems with time-varying delay is investigated. The observer system is configured with periodic piecewise polynomial character to concurrently reconstruct the actuator faults and states of the system. Based on these configurations, the fault-tolerant tracking control is proposed, which aids in tracking the reference system by compensating the actuator faults. Numerical example is provided to validate the competence of proposed control scheme.

[01540] Composite Disturbance Rejection and Stabilization for Periodic Control Systems

Session Date & Time : 1C (Aug.21, 13:20-15:00)
Type : Contributed Talk
Abstract : The stabilization and disturbance rejection issues for periodic control systems with actuator faults and external disturbances are investigated through a proportional integral observer approach. An equivalent-input-disturbance approach is employed to estimate the external disturbances. Moreover, proportional integral observer provides more design freedom and enhances the estimation precision of equivalent-input-disturbance. A periodic time-varying control framework is proposed to guarantee robust performance of the system. The potential of the proposed control design is validated via numerical simulations.

[01542] Bipartite synchronization of complex dynamical networks under hybrid-triggered control

Session Date & Time : 1C (Aug.21, 13:20-15:00)
Type : Contributed Talk
Abstract : The bipartite synchronization problem for multi-weighted complex dynamical networks subject to random coupling delays and external disturbances is investigated. For this, a hybrid-triggered control is incorporated, which in addition, is effective in the reduction of network resource usage guaranteeing the system’s performance. And, the external disturbances are attenuated under extended passivity performance. Moreover, the conditions for ensuring the requisite synchronization of undertaken networks are derived. A numerical example is illustrated to validate the results obtained.

[01544] Unknown Input Observer-based Multiple Faults Reconstruction for Interval Type-2 Fuzzy-Model

Session Date & Time : 1D (Aug.21, 15:30-17:10)
Type : Contributed Talk
Abstract : The prime intent of this study is to resolve the multiple faults reconstruction and state tracking issues for the interval type-2 fuzzy systems subject to actuator and sensor faults by using an active fault-tolerant tracking control law based on an unknown input observer approach. Moreover, a set of sufficient conditions namely linear matrix inequality is derived to ensure the tracking performance of the addressed system. Eventually, the derived theoretical results are verified through numerical examples.

[01546] Input-output Finite-time Stabilization for Parabolic PDE Systems with Semi-Markov Switching

Session Date & Time : 1D (Aug.21, 15:30-17:10)
Type : Contributed Talk
Abstract : A robust reliable boundary control problem for a class of parabolic PDE systems with semi-Markov switching subject to actuator faults, randomly occurring uncertainties and nonlinearities is investigated. Particularly, randomness phenomena are characterized by stochastic variables obeying Bernoulli distribution properties. A boundary controller is developed to ensure the robust performance of the considered system. Sufficient conditions for guaranteeing the input-output finite-time stabilization of the closed-loop system are derived. Proposed method is validated through simulation outcomes.

Type : Contributed Talk
Abstract : The issues of input-output finite-time stabilization and state estimation for a class of semi-Markovian switching cyber-physical systems with cyber-attacks are investigated. Primarily, immeasurable states are estimated by designing a mode-dependent observer. Further, based on the observer information, mode-dependent time-triggered controller is developed to ensure that the resultant system is input-output finite-time stable. Finally, the efficacy of proposed result is demonstrated through a numerical example.

[01564] Extended Observer-based Control for Interval-type-2 Fuzzy Systems Under Event-Triggered Scheme

Session Date & Time : 1D (Aug.21, 15:30-17:10)
Type : Contributed Talk
Abstract : The problems of disturbance rejection and fault tolerant control for interval-type-2-fuzzy systems are investigated by utilization of a generalized extended state observer. To be specific, the system states along with disturbances and actuator faults are simultaneously reconstructed by the implemented observer. Besides, an observer-based event-triggered scheme is implemented to mitigate the communication burden. Furthermore, the asymptotic stability criteria for the constructed system are formulated. Consequently, the theoretical declarations are authenticated by prevailing numerical simulation results.
