Genetic-Algorithm-Based Feedwater Control System of Drum Boiler

Cascade three- element feedwater control system is adapted to regulate the drum water level. Genetic algorithm (GA) is in- troduced to tune the system in order to obtain the optimal parameters. SIMULINK simulation results show that the GA- optimized feedwater control system is able to reject endogenous and exogenous disturbances more effectively and rapidly, compared to the con- ventional tuning method.
