Intelligent Based Controllers for Multivariable Boiler Turbine Systems

Deepa T, Lakshmi P and Balaji V

The paper presents the Co-ordinated controller design of boiler turbine unit. Co-ordinated controller design is a conventional method, that controller values are optimized using the optimization techniques like Particle Swarm Optimization (PSO) and Genetic Algorithm (GA) in dynamic system. A complete analysis for each technique is presented in time domain. Performance of both controllers is examined and control performance measures for common input changes. Integral Square Error (ISE) is used as performance index for designing the controllers. Finally, a comparative assessment of each controller on the system performance is presented and discussed. From the results, it is inferred that the performance of PSO gives minimum Integral Square Error (ISE).
