Modeling And Control System Optimization Of Coordinate System In CFB Boiler Based On PSO Algorithm

This thesis focused on the modeling and controller optimization of the coordinate system in circulating fluidized bed (CFB) boiler. Based on the particle swarm optimization algorithm , a MIMO linear transfer function model was built with the history operating data of a 50MW CFB unit., then according to the unit model based on the way of boiler with turbine coordinate control system, and using particle swarm optimization algorithm is completed controller parameters optimization. Simulation results show that this method is good at solving the CFB boiler coordination system modeling and control problems,the control effect is good. And in this paper, the identification and optimization method can be applied to other thermal system to solve this kind of complex, automatic control system of guiding significance.
