Speed Control Scheme Analysis of Switched Reluctance Actuator

Pestana L., Calado M., Mariano S.

Przegląd Elektrotechniczny

2012

R. 88, nr 1a

173-176

This paper presents the implementation of a nonlinear model of a Linear Switched Reluctance Actuator (LRSA) in Simulink/ SimPowerSystems environment. The model is based in an already implemented motor model for the rotating machine, which was improved and adopted to be applied in the analysis of a linear actuator. Both the magnetic information from experimental data and results obtained from Finite Element Analysis (FEA) were used to perform that analysis. The model is used in the assessment of several control schemes.

Przedstawiono nieliniowy model liniowego siłownika reluktancyjnego LRSA z wykorzystaniem środowiska Simulink/SimPowerSystem. Do analizy wykorzystuje się dane eksperymentalne i obliczone przy wykorzystaniu metody elementu skończonego.

Modeling and simulation of indoor environment and building energy performance

Contemporary development of architectural engineering and building services providing building operation is related to energy supply and use. The level of building dependence on energy is given by architect's priorities during conceptual design phase. Within existing traditional buildings it is possible to predict energy and environmental performance using empirical formulas, experience and simplified models, while within modern buildings it is difficult to describe synergy performance of particular building energy systems and its impact on indoor environment quality and energy performance. For these and other cases it is possible to use numerical modelling of building energy systems and create virtual laboratory to perform experiments with the building and to optimise building design. Different viewpoints are used to classify tools for building simulation. According to the method, detail level and model purpose following classes are classified: static models, simplified dynamic models, response function models, numerical methods models, analogy with electrical circuits and CFD (computational fluid dynamics) models. Keywords: performance simulation, low-energy building.
