Because combustion efficiency increases with rising of bed temperature and also harmful emissions are affected by bed temperature. Classical PID controller can't give fast response to instant changes in boiler. So modern control methods must be used for bed temperature control of circulating fluidized bed boiler. In this study PSO-PID (Particle Swarm Optimization based PID), FLC which are modern controllers, and classical PID controller are used for controlling bed temperature of a circulating fluidized bed boiler and they are compared. Simulation results show that settling time in PSO-PID controller is lower than the other controllers. PSO-PID decreases overshoot like FLC but in classical PID controller overshoots are the biggest. In FLC there are no overshoot. So if overshoot isn't wanted, a FLC must be used and if short settling time is wanted, a PSO-PID controller must be used. © 2011 Chamber of Turkish Electric.eninfo:eu-repo/semantics/closedAccessElectric control equipmentElectronics engineeringBed temperatureCirculating fluidized bed boilerCombustion efficienciesFast responseHarmful emissionsModern controlPID controllersSettling timePulverized fuel fired boilersConference Object2-s2.0-84857241912II380N/AII376
