This paper deals with the development of a mathematical dynamic model and observer-based set point control of a vapor compression cycle (VCC) system. The mean void fraction and moving boundary control volumes in a heat exchanger (HEX) are used for a lumped parameter model of an air conditioning system. A multi-input multi-output (MIMO) dynamic model of the VCC is presented in a nonlinear state space...
In this paper, we control an air conditioner system thought the application of a newly developed Intelligent Proportional Integral (i-PI) Controller that regulate a zone temperature to desired setpoint temperature. This method approximates the unknown nonlinear system function and is applied to the problem of controlling compressor for a vapor compression cycle system where evaporating pressure target...
This paper deals with an adaptive robust tracking control using a multilayer neural network (NN) for a class of nonlinear dynamic systems with unknown time varying state delays. Typical adaptive NN backstepping controllers for uncertain nonlinear systems with time-delay give rise to computation complexity caused by the the repeated derivatives of virtual controllers and nonlinear functions. Moreover,...
The aim of this research is to develop an intelligent tutoring system (ITS) which teaches students the causal relationships between the components of the circulatory physiology system and the complex behavior of the negative feedback system that stabilizes blood pressure. This system will accept natural language input from students and generate limited natural language explanations. It contains rules...
