This paper describes a power system inertia estimation method that utilizes perturbations caused by the flow switch on an HVDC interconnector. The analysis is performed using real measurements from Ireland's all-island system. employs energy based technique which permits non-step change to be used for calculation and encapsulates challenges associated with use of data. While it shown synchronou...

The localized electron cyclotron resonance heating power that can suppress sawteeth reconnection often drives m = 2 tearing modes in a tokamak operating at constant current. The dynamics of mode onset and coupled mode evolution is described in detail and compared with a nonlinear theoretical model that identifies the effects of mode coupling, finite inertia of the rotating islands, and wall bra...

In previous papers authors have considered agents as inertia-less self driven particles and designed a flocking algorithm. Application of this algorithm to agents with considerable inertial characteristics needs a behavioural controller. The controller uses the local information and helps every agent to imitate the desired behaviour as a member of the flocking frame which covers the main is...

The important and hazardous of the rescue mission in oceans and seas, autonomous vessels now are one of the most appropriate applications among others. Due to safety, reliability, and accessibility of smart, Autonomous and Cooperative vessels today has attracted much attention from the industry. Regard to the complication of the mono vessel for different objects, the multi- agent system was pro...

This paper aims at investigating the nonlinear behavior of a system which is consisting of two free-free beams which are connected by a nonlinear joint. The nonlinear system is modelled as an in-extensional beam with Timoshenko beam theory. In addition, large amplitude vibration assumption is taken into account in order to obtain exact results. The nonlinear assumption in the system necessities...

Within the framework of [Formula: see text] theories gravity, we investigate hydrostatic equilibrium anisotropic neutron stars with a physically relevant equation state (EoS) for radial pressure. In particular, focus on model, where is minimal coupling constant. slowly rotating approximation, derive modified TOV equations and expression relativistic moment inertia. The main properties stars, su...

in this research, the total torque input and output shafts were subjected to are used to formulate twodifferential equations using applied dynamics and fluid mechanics. the equations show that the input andoutput torques are a function of the constant geometrical parameters of a torque converter, includinginternal and external diameters of vanes, angle and length of vanes, cross section area be...

This paper investigates the problem of output feedback attitude control for rigid spacecraft subject to inertia matrix uncertainty, space disturbance, and input saturation. Firstly, a model transformation is adopted convert an system with immeasurable angular velocity into new system. All states converted are measurable available feedback; however, contains mismatched uncertainty resulting from...

The interaction of work fluid mechanics with that of the rotary system itself, basically composed of axes, bearings and rotors, is performed by inserting equivalent dynamic coefficients in the mathematical model of the rotor, the latter being obtained by the finite element method. In this paper, the dynamic coefficients of inertia, stiffness and damping of the flat seals analyzed here are evalu...
