Port-Hamiltonian systems (PHS) are an extension of Hamiltonian systems, which represent open passive systems which are structured according to their conservative and dissipative parts, as well as the external sources. They are widely used in engineering as a central tool for the modelling of physical systems, their passive-guaranteed simulation, as well as for control issues, see e.g. [1]. In t...

concurrency control is one of the important problems in operation systems. various studies have been reported to present different algorithms to address this problem, although a few attempts have been made to represent an overall view of the characteristics of these algorithms and comparison of their capabilities to each other. this paper presents a survey of the current methods for controlling...

This thesis explores the dynamics of two mechanical systems capable of performing their tasks without the use of active control. The first system is an autobalancer, which can continuously balance rotating machinery. This is accomplished by using compensating masses that move in a viscous media about the axis of rotation. The second system is a passive bipedal walker, capable of human like gait...

This paper investigates the problem of passive delayed static output feedback control for a class of fuzzy systems. The system is described by a statespace Takagi–Sugeno (T-S) fuzzy model with additive delays and interval parameter uncertainties. The aim is to design a fuzzy delayed static output feedback controller which ensures the closed-loop system is passive for all admissible uncertaintie...

This paper proposes an intelligent model for realtime control of the hygrothermal behaviour in low energy buildings. Through the management of information related to internal and external conditions combined with the design and context data, the built network lead to assess the correct strategy for an adequate hygrothermal behaviour (choosing between active and passive systems for control of in...

This paper investigates the problem of non-fragile observer-based passive control for descriptor systems with time-delay. The perturbations in both the control gain and observer gain of the observer-based controller are considered. For the cases of the additive perturbations and multiplicative perturbations, sufficient conditions are given such that the closed-loop systems are admissible and pa...

In the design of bridges with large spans, the significant values of the moments at the main deck-structure require very heavy members, either in the case of a beam or a truss deck-structure. In order to minimize the influence of bending moments, several applications of passive control of displacements using cable nets are herein proposed. The base for all the proposed systems is the cables sup...

The utilization of passive energy dissipation systems has been created a revolution in the structural engineering industry due to their advantages. Fluid Viscous Damper (FVD) is one of these control systems. It has been used in many different industries, such as the army, aerospace, bridge, and building structures. One of the essential questions about this system is how it can combine with the ...

Event-triggered control has been recently proposed as an alternative to the traditional periodic implementation of control tasks. The possibility of reducing the number of executions while guaranteeing stability makes event-triggered control very appealing in the context of sensor/actuator networks. In this paper, we revisit the event-triggered control from an input-to-output perspective and we...
