This paper is concerned with the problems of admissibility and control for a class of discrete-time switched singular systems with time-delay for arbitrary switching law. Firstly, a new delay-dependent sufficient condition is established in terms of linear matrix inequalities (LMIs) by constructing a novel Lyapunov-Krasovskii functional so that the discrete-time switched singular systems with time-delay to be regular, causal and asymptotically stable. The proposed criterion is proved to have some advantages over other existing results. Then, a state feedback controller is designed to guarantee the admissibility of the closed-loop switched singular delay system, by using the skills of matrix theory. Some slack variables are introduced for more relaxation. Finally, numerical examples are provided to demonstrate the effectiveness of the proposed approach and to compare the obtained results with some existing ones in the literature.

Chaos phenomena can be found in many scientific disciplines such as astronomy, biology, chemistry, engineering, geology, mathematics, medicine, meteorology, and even social sciences. Such phenomena can seriously affect the behaviour of some vital applications such as communications and security systems. Hence, a controller is required to handle chaotic behaviours that affect systems stability. In this paper, a robust output feedback controller is proposed to stabilise electronic circuits used in communications and security systems that exhibit chaotic behaviours. The proposed controller is designed to deal with unknown system parameters and time-varying uncertainties. Only the system output is utilised in the proposed controller while estimating the system states. For that purpose, a high gain observer is designed and utilised to estimate the unknown states. In addition, a numerical study is introduced to demonstrate the robustness and effectiveness of the controller design under various system configurations and different operating conditions. As a result, a satisfactory tracking performance is observed.

This study presents a control strategy for grid-connected WES based on a permanent magnet synchronous generator (PMSG). The power system comprises five PMSG-based 2 MW which connected to the dc-bus with rectifiers, whereas the grid-side inverter is connected to the power grid throughout a grid-side filter. The objectives of grid-side inverter are to deliver the energy from the PMSGs side to the power grid, to regulate the dc-bus and to achieve unity power factor (UPF). The generator side converters are employed to control the velocities of the PMSGs with maximum power point tracking algorithm. Moreover, a pitch control algorithm is used. The proposed vector control technique (VCT) is able to fully decouple the quadrature (q) and direct (d) components of the currents. Simulations results using MATLAB/Simulink software are presented to validate the proposed control scheme for fault conditions into the grid as well as for normal working conditions.

This paper studies an adaptive tracking control for a class of multi-input multi-output (MIMO) non-affine nonlinear systems, with input dead-zone nonlinearity and external disturbances. By using the mean-value theorem, the system model is transformed into an affine form so as the difficulty in controlling non-affine systems is overcome. In the proposed control design, neural networks (NNs) are used to approximate the unknown nonlinearities based on their universal approximation properties. To compensate for approximation errors and external disturbances, an adaptive robust control term is introduced. In comparison with existing approaches, the structure of the designed controller is considerably simpler, and can handle a wider range of nonlinear systems. The stability of the closed-loop system is investigated by using Lyapunov theory. The simulation results illustrate the proposed method.

Due to the tiny size, nodes in a wireless sensor network (WSN) are restricted in battery capacity. As a result, a node and in turn a network of such nodes is not operational for a long time. Further, in some hostile area, battery cannot be replaced easily once deployed. Therefore, an energy conservation scheme or algorithm is needed to prolong the network lifetime. In this paper, an energy efficient routing scheme (EERS) is proposed and evaluated. This scheme extends the lifetime of network by selecting the finest shortest path to transmit data packets to the destined nodes. EERS selects a path/quality link over which it has minimum number of hops with maximum remaining energy over that path. Proposed scheme EERS is compared with other existing schemes for different parameters and varying size of network (1001,000 nodes). The simulation results shows that the EERS scheme prolongs the network lifetime 10%-15% as compared to other considered schemes. EERS also minimises the delay for transmitting data packets and increases the packet delivery ratio.

The analysis of higher order systems is tedious and cumbersome task. This motivated analysts to reduce higher order systems into lower order models using mathematical approaches. In this paper, an analytic hierarchy process (AHP)-based approximation of stable higher order systems to stable lower order models using sine cosine algorithm (SCA) is presented. The stable approximant is deduced by minimising the relative errors in between time moments and Markov parameters of the system and its approximant. In order to match the steady states of the system and its approximant, the first time moment of the system is retained in the approximant. AHP is utilised to convert multi-objective problem of minimisation of errors in between time moments and Markov parameters into a single objective problem by proper assignment of weights. To ensure the stability of the approximant, Hurwitz criterion is utilised. The systematic nature and efficacy of the proposed technique is validated by deriving approximants for three different test systems.
