Design of Intelligent Predictive Controller for Electrically Heated Micro Heat Exchanger

Abstract

Abstract. An intelligent predictive control with locally linear neurofuzzy identifier and numerically optimization procedure has been proposed for temperature control of electrically heated micro heat exchanger. To this end, first the dynamics of the micro heat exchanger is identified using Locally Linear Model Tree (LOLIMOT) algorithm. Then, the predictive control strategy based on the LOLIMOT model of the plant is applied to provide set point tracking of the output of the plant. Some computer simulation is provided to show the effectiveness of the proposed controller. Simulation results show better performance for the proposed controller in comparison with PID controller.

Improved Design of Microchannel Plate Geometry for Uniform Flow Distribution

“…Hardt et al (2003) carried out studies of enhancing heat transfer in microchannels with fi ns in a checkerboard arrangement. The idea of different optimization techniques and model predictive control concepts was also applied to control the output temperature in micro heat exchangers (Okabe et al, 2003 andRoudsari et al, 2005). A substantial research has also been done in micro cross-fl ow heat exchangers (Harris et al, 2002).…”
