The model predictive control of turbo charging unit of pressurized marine boiler

摘要

This paper mainly outline the control problem of the turbo-charging unit of the pressurized marine boiler. Unlike the conventional marine boiler, the biggest difference of the pressurized marine boiler is the turbo-charging unit it is have. The turbo-charging unit is the key part of the pressurized marine boiler and its function is to supply the steam power plant enough air to make sure the sufficient burning's maintenance in the furnace of the boiler. The structure of the turbo-charging unit is of high complexity and the parameters variation with the working condition transformation, which makes it is difficultly to control the unit operating in the way we desire. In order to improve the control performance, we present a predictive controller and the simulation results demonstrate the controller make good performance.
