[00046] Global exponential synchronization of complex-valued recurrent neural networks with time-varying bounded and unbounded delay terms

- Type : Contributed Talk
- Abstract : The global exponential synchronization criteria of complex-valued recurrent neural networks (CVRNNs) in presence of uncertain parameters with time-varying bounded and unbounded delay terms have been investigated. Based on Halanay inequality and matrix measure approach, the global exponential synchronization is studied. The synchronization of CVRNNs is achieved with help of Lyapunov functional, and several sufficient criteria and theorems. Finally, two numerical examples are taken to show viability and unwavering quality of our results for various cases.

[00051] Finite-time synchronization of multi-scroll chaotic systems with sigmoid non-linearity and uncertain terms
- Session Date & Time : 2C (Aug.22, 13:20-15:00)
- Type : Contributed Talk
- Abstract : Finite-time synchronization of multi-scroll chaotic systems with sigmoid non-linearity in the presence of uncertain stochastic parameters has been studied. The present chaotic system scrolls (up to five) are incorporated with the help of hyperbolic tangent functions, but in real applications, there is no limit of multi-scroll in a chaotic system. Finite-time synchronization is achieved with the help of Lyapunov stability using some lemmas and definitions. The Lyapunov exponents are also calculated for multi-scroll chaotic systems.

[01005] Nonlinear Disturbance Observer-Based Control Design for Markovian Jump Systems
- Session Date & Time : 2C (Aug.22, 13:20-15:00)
- Type : Contributed Talk
- Abstract : This paper addresses the anti-disturbance control problem for time-delayed Markovian jump nonlinear systems with modeled and unmodeled disturbances. Specifically, the modeled disturbance is generated by a nonlinear exogenous system and estimated using a nonlinear disturbance observer. A mode-dependent asymmetric Lyapunov-Krasovskii functional is used to derive sufficient conditions for the existence of the proposed controller and disturbance observer. A numerical example is included to demonstrate the efficacy of the theoretical results developed.

[01012] Uncertainty and disturbance estimator design for interval type-2 fuzzy systems
- Session Date & Time : 2C (Aug.22, 13:20-15:00)
- Type : Contributed Talk
- Abstract : This article investigates the uncertainty and disturbance estimator-based control problem for the interval type-2 fuzzy systems. By designing the appropriate filter, the proposed control designs can estimate system uncertainties and external disturbances accurately. By using the Lyapunov-Krasovskii stability theorem, the required stability conditions and the control gain matrices for the system under consideration are obtained. Finally, an illustrative example is demonstrated to verify the feasibility of the proposed control method.

[01014] Fault detection asynchronous filter design for Markovian jump fuzzy systems under cyber attacks
- Session Date & Time : 2C (Aug.22, 13:20-15:00)
- Type : Contributed Talk
- Abstract : This work is concerned with the issue of fault detection asynchronous filter design for a class of discrete-time Markovian jump fuzzy systems with cyber attacks. Precisely, the cyber attacks phenomenon in the network environment satisfies the Bernoulli distribution. Finally, the applicability and usefulness of the proposed filter design method is verified through a practical example.

[01059] EVENT-TRIGGERED CONTROL FOR PARABOLIC PARTIAL DIFFERENTIAL EQUATIONS WITH CYBER-ATTACKS
- Session Date & Time : 2D (Aug.22, 15:30-17:10)
- Type : Contributed Talk
- Abstract : An event-triggered control for parabolic-type partial differential equations subject to disturbances and cyber-attacks is addressed in this talk. To attenuate the disturbances an H∞ performance is considered. By designing an appropriate Lyapunov-Krasovskii functional the stabilization conditions for the considered parabolic type partial differential equations are obtained in the form of linear matrix inequalities. Finally, a numerical example is provided to verify the efficiency of the derived theoretical results.

[01008] EID estimator-based Control Design for Singular Polynomial Fuzzy Systems
- Session Date & Time : 2D (Aug.22, 15:30-17:10)
- Type : Contributed Talk
- Abstract : This paper studied the disturbance rejection problem for singular polynomial fuzzy system based on equivalent-input-disturbance-estimator-based control approach. The proposed approach is used to compensate the influences of unknown lumped disturbance. To cope the robust stability problems, the augmented closed-loop system is constructed that includes dynamics of the system, observer, and low-pass filter. Lyapunov stability theory is used to develop stability conditions for the resulting system. Finally, numerical examples are provided to validate the theoretical result.

[00590] Feedback control of propagating bubbles: stabilization and control-based continuation
- Session Date & Time : 2D (Aug.22, 15:30-17:10)
- Type : Contributed Talk
- Abstract : We study the propagation of air bubbles into fluid filled Hele-Shaw channels. Feedback control is used to manipulate the system to a desired configuration and also as a tool to explore the full range of nonlinear behaviour. Control is implemented by the addition of time-dependent fluid injection along the channel. Control-based continuation allows unstable steady states to be observed and stabilised directly in our time-dependent simulations. Steady and time-dependent simulations are performed using finite elements.

[00655] Finite-time fault-tolerant robust control design for parabolic partial differential equations
- Session Date & Time : 2D (Aug.22, 15:30-17:10)
- Type : Contributed Talk
- Abstract : In this paper, a finite-time fault-tolerant robust control design for parabolic partial differential equations in the presence of uncertainties, actuator faults and external disturbances is discussed. The main aim is to design a non-fragile fault-tolerant control to ensure the robust stabilization of the considered PDEs. By employing Lyapunov method, a novel set of conditions is obtained to ensure the required result. Finally, simulations are provided to demonstrate the effectiveness of the developed control design.

[02605] Lie-bracket-based feedback stabilizability with cost regulation
- Session Date & Time : 2D (Aug.22, 15:30-17:10)
- Type : Contributed Talk
- Abstract : For an optimal control problem where the state has to approach asymptotically a target while paying a cost, we propose a generalization of the dissipative relation that defines a Control Lyapunov Function to a weaker differential inequality. It involves both the cost and the Lie brackets of the dynamics’ vector fields. We prove that the existence of a suitably defined solution to such inequality implies feedback stabilizability and a uniform bound on the cost.
