BOILER DRUM LEVEL CONTROL USING FRACTIONAL ORDER PID CONTROLLER WITH DCS SW APPLICATION

Abstract

This research work aims at developing a control scheme for boiler drum level in steam power plant. A conventional Proportional-Integral-Derivative (PID) controller and Fractional Order Proportional-Integral-Derivative (FOPID) controller are used to regulate the drum level for a three elements scheme. SIMULINK package is used to simulate different models and controllers for different disturbances. A distributed Control System (DCS) SW package from ABB has been used to simulate the controllers and the boiler drum level process. Graphic display have been developed to visualize the results and tuning of controller parameters. Results indicate the effectiveness of FOPID over PID controller in improving the dynamic performance.
