Predictive Control of Gas Injection in Natural Gas Transport Networks

The present sought to draw a comparison between Model Predictive Control performance and two other controllers named Simple PI and Selective PI in controlling large-scale natural gas transport networks. A nonlinear dynamic model of representative gas pipeline was derived from pipeline governing rules and simulated in SIMULINK® environment of MATLAB®. Control schemes were designed to provide a s...

Automatic Control of the Software Development Process with Regard to Risk Analysis

Greedy Algorithms with Regard to Multivariate Systems with Special Structure

Department of Mathematics, University of South Carolina, Columbia, SC 29208 Abstract. The question of finding an optimal dictionary for nonlinear m-term approximation is studied in the paper. We consider this problem in the periodic multivariate (d variables) case for classes of functions with mixed smoothness. We prove that the well known dictionary U which consists of trigonometric polynomial...

Designing a new robust control for virtual inertia control in the microgrid with regard to virtual damping

Background and Objectives: Virtual inertia control, as a component of a virtual synchronous generator, is used for the implementation of synchronous generator behaviour in microgrids. In microgrids that include high-capacity distributed generation resources, in addition to virtual inertia, virtual damping can also lead to improvement of frequency stability of the microgrid. The purpose of the c...
