Performance analysis of hybrid fuzzy-PID controller action on boiler drum level control

Boiler unit plays a vital role in power plant and controlling the boiler drum level is one of the critical operations. Nowadays, Fuzzy Logic controller or Conventional PID controller is designed in MATLAB simulation and further prototype is implemented using Embedded Technology, hybrid platform is required in power plant. To overcome this and to get better solution intelligent controller (fuzzy logic) is used to tune the conventional PID controller automatically in online process. Hybrid Fuzzy-PID controller result proves that, it offer better performance (in terms of settling time, rising time, steady state error) than conventional PID controller in boiler drum level control. The simulation results are achieved by using LabVIEW Fuzzy-PID Tool.
