Boiler Flow Control Using PID and Fuzzy Logic Controller
نویسندگان
چکیده
Conventional Proportional Integral Controllers are used in many industrial applications due to their simplicity and robustness. The parameters of the various industrial processes are subjected to change due to change in the environment. These parameters may be categorized as steam, pressure, temperature of the industrial machinery in use. Various process control techniques are being developed to control these variables. In this paper, the steam flow parameters of a boiler are controlled using conventional PID controller and then optimized using fuzzy logic controller. The comparative results show the better results when fuzzy logic controller is used. Maximum overshoot for fuzzy logic controller is measured as 9.35% as compared with 47.3% given by conventional PID controller. Settling time for fuzzy logic controller and PID controller is measured at 7.18 seconds and 10.14 seconds respectively, which shows the superiority of fuzzy logic controller.

Hybrid Fuzzy-PID Application in Boilers to Obtain Optimum Efficiency
Many real time processes have complex, uncertain and nonlinear dynamics. Boilers are nonlinear, time varying, multi-input multi-output (MIMO) systems, whose states generally vary with operating conditions. The major problem in controlling that system is that its drum water pressure and steam flow dynamics include an integrator that results a critically stable behavior. Conventional controller p...
متن کاملApplication of hybrid fuzzy logic proportional plus conventional integral-derivative controller to combustion control of stoker-fired boilers
Combustion control of an industrial stoker-"red boiler is to provide a continuous supply of steam at the desired condition of pressure. Because no e$cient mathematical model of the stoker-"red boiler is available, it would be very hard to design its controller by using any traditional model-based method. Therefore, the most widely used controller for the boiler system is a conventional PID-type...

متن کاملModeling and Simulation of a Fuzzy Supervisory Controller for an Industrial Boiler
In this paper we compare and discuss the performance of a boiler evaporator system when the system is controlled by a traditional PID-type strategy and when the system is enhanced by using fuzzy logic blocks to provide set-points for the system. The strategy used in fuzzy logic controllers (FLCs) is called fuzzy supervisory control and it generates set-points for the conventional controllers. T...
