In this paper, the Adaptive Generalized Minimum Variance (AGMVC) is designed to control a Single Input Single Output (SISO) of central heating process by adjusting the flow of hot fluid through a valve driven by an electric voltage input. The model of the process has been obtained by an on- line algorithm identification using the Recursive Least-Squares estimation technique (RLS).
Production systems of renewable energy are extensively studied because of their major interest in sustainable development. Therefore, the control structures of the inverter connected to the network is an important part of the conversion and transmission of energy, they must be improved to meet the demands of the connection to the distribution network. This article discusses the comparison between two structures of three-phase inverters; NPC three-level inverter (Neutral Point Clamped), and the usual two-level inverter. The comparison is based on the evaluation of harmonic distortion THD for both inverters are controlled by two different strategies, namely sinusoidal pulse with modulation SPWM and control in mode SWM (square-wave mode). All circuits are modeled and simulated using Matlab-Simulink-SimPowerSystems software.
