Robust nonlinear control experiment performance analysis of a semiconductor refrigeration device

摘要

In this paper, an operator-based robust perfect control for nonlinear semiconductor refrigeration device with uncertainties is considered. For the research about the properties of the semiconductor refrigeration, an aluminum plate with Peltier device is very representative. So, the perfect tracking control performance is investigated by using this device. The robust right coprime factorization approach is convenient in analysis and design for the nonlinear system with uncertainties, based on this reason, the operator-based robust right coprime factorization approach and operator-based observer are used. First, something about semiconductor refrigeration devices and operator-based robust right coprime factorization approach has been introduced. Second, basic conceptions and methods about operator method and robust right coprime factorization approach are described in rough. Third, a perfect tracking control design is given, the robust stability of the system is guaranteed and the perfect tracking performance can be achieved. Finally, the effectiveness of the design scheme is demonstrated by an experiment for the aluminum plate with Peltier device.
