This paper is concerned with set-point sevo problems by P·SPR·D control and P·I·SPR·D control of affine nonlinear system which is of multi input and multi output. P·SPR·D control consists of proportional (P) action + strict positive real (SPR) action + derivative (D) action. Such control can asymptotically stabilize the affine nonlinear system being passive. Stability analysis of P·SPR·D contro...

<span>Due to the need for multicast connection required by multimedia applications such as video conferencing and natural disaster management, it was necessary use a set of portable connected wireless peripheral devices without infrastructure central router, network "a mobile ad hoc (MANET) " Despite difficulties facing this technology in process effective guidance expansion networks, typ...

Cassia tora Linn. is one of the well-known anthraquinone containing plant and has been used in Chinese and Ayurvedic medicine. In the present review, an attempt has been made to explore a literature survey on its traditional uses, phytochemical studies and pharmacological properties. The whole plant as well as specific parts such as roots, leaves and seeds have been widely used and claimed agai...

In this paper, we consider the nonlinear benchmark problem. First, we construct the Takagi-Sugeno model using sectorization of the nonlinearity. Then by utilizing the concept of "parallel distributed compensation", we present the design of the fuzzy controller. The design procedure we adopt is to convert the design of the controller to a linear matrix inequality (LMI) problems so that the stabi...

For T-S fuzzy systems with hard constraints and disturbances modeled by impulses, a constrained H2 control scheme in the framework of LMI (Linear Matrix Inequality) optimization is proposed in this paper. First, the H2 norm is chosen as measurement of disturbance attenuation level, and sufficient conditions for guaranteeing an H2 performance are given. Then, under the bound assumption of the di...

Abstract: In this work, we consider the feedback stabilization problem of the so-called Translational Oscillator with a Rotational Actuator (TORA) system by applying the Interconnection and Damping Assignment (IDA) control methodology. To achieve this goal, the mechanical system is firstly transformed into the general port controlled Hamiltonian form and, then, the IDA design procedure is appli...

The present paper proposes an approximation method to solve the problem of approximate nonlinear output regulation. In this approach, the solution of the regulator equations, consists of partial differential equations and an algebraic equation, is analytically approximated by Galerkin approximation method. The proposed method is general and can be applied on a wide class of nonlinear systems th...

A Wireless sensor network of globally distributed autonomous sensors to monitor physical or environmental conditions such as temperature, noise, pressure etc. and to cooperatively pass their data through the network to a main location. CASER protocol is used to increase the lifetime of the network. Energy consumption and security are the two conflicting issues in WSN. To overcome this problem s...
