the dynamic nature of projects and the fact that they are carried out in changing environments, justify the need for their periodic monitoring and control. collection of information about the performance of projects at control points costs money. the corrective actions that may need to be taken to bring the project in line with the plan also costs money. on the other hand, penalties are usually...

Aim. This work presents the amelioration of direct power control using synergetic-super twisting algorithms for asynchronous generators integrated into dual-rotor wind turbine systems. Method. The main role is to active and reactive powers reduce harmonic distortion stator current generator variable speed traditional strategy more attractive due its high efficiency simple algorithm. Super are a...

This paper proposes decentralized improved synergetic excitation controllers (ISEC) for synchronous generators to enhance transient stability and obtain satisfactory voltage regulation performance of power systems. Each generator is considered as a subsystem, for which an ISEC is designed. According to the control objectives, a manifold, which is a linear combination of the deviation of generat...

This paper summarizes the work on road vehicle motion control, with focus on different strategies to achieve synergetic effects for over-actuated systems, and gives an overview of related work, especially from aircraft and robotics research. A systematic categorization of the strategies with respect to the physical principles of the motion generation, the realm of the control action and the con...

This paper analyses the 500 most frequent verbs in contemporary Chinese and investigates their synergetic properties. The results show that the rank-frequency distributions of both valency and polysemy abide by a power-law distribution and that valency and polysemy of these verbs abide by the Good distribution and the positive negative binomial distribution respectively. Statistical analysis in...

During the underground mining of coal resources, rock pressure emerges acutely and mine geological disasters occur frequently. It is great significance to grasp manifestation law in time guide safety production operation pit. In this research, calculation equations concept information entropy based on zone degree are primarily defined, synergetic theory maximum principle combined put forward sy...

the present study deals with the oral supplementation with (50, 100 and 150 ?g/ml) synergetic effect of potassium and magnesium chloride on the fat body glycogen, protein, total lipids and haemolymph trehalose, protein of fifth instar larvae of bombyx mori l (lepidoptera: bombycidae). the observed parameters significantly increased in all the treated groups when compared with those of the corre...
