Robust Control Of Air-Flow In Air-Heating Set
نویسنده
چکیده
The paper deals with the robust control of air-flow in air-heating set. The identification is perrfomred using step responses and approximation via second order system. The controller is designed using the structured singular value (SSV or μ) and algebraic approach. Since the cost function is nonconvex the optimization cannot be done using standard tools. Hence an evolutionary algorithm Differential Migration (DM) is employed yielding good results in this case. The functionality of the comtroller is verified though experiments on the real plant.

Temperature Decline in Embryological Culture Dishes outside Incubator
Background: In embryological culture dishes, there is a temperature decline when they are removed outside incubators. This study aimed at investigating the effects of this temperature decline within a certain time frame, the type of culture dish with or without the use of laminar air flow and whether it is possible to achieve a sufficient thermal control with the use of a heating stage. Materia...
متن کاملMIMO Robust Control for Heating, Ventilating and Air Conditioning (HVAC) Systems
Potential improvements in heating, ventilating, and air conditioning (HVAC) system performance are investigated through the application of multiple-input, multiple-output (MIMO) robust controllers. This approach differs dramatically from today’s prevalent method of building HVAC controllers using multiple single-input, single-output (SISO) control loops. A simulation model of an experimental HV...

In order to achieve feasible and copacetic low energy consuming building, a robust and efficient air conditioning system is necessary. Since heating ventilation and air conditioning systems are nonlinear and temperature and humidity are coupled, application of conventional control is inappropriate. A multi-input multi-output nonlinear model is presented. The temperature and humidity of thermal ...
