Abstract

PID controller is employed in every facet of industrial automation. . It is natural that it is necessary to improve quality of any production technology in a complex way, by means of replacing the technology itself, as well as by continuous optimization of operation. It is just here, where new opportunities of using fuzzy controller are opening, as a compensation for a man in control and optimizing processes. This paper presents design of PID controller using Ziegler-Nichols (ZN) technique and Fuzzy controller for isolated steam turbine. PID controller tuning using PSO is proposed in this paper. Simulation results are demonstrated. Performance analysis shows the effectiveness of the proposed Fuzzy logic controller as compared to the ZN tuned PID controller and and tuning by using particle swarm optimization.
