Multivariable generalized predictive scheme for gas turbine control in combined cycle power plant

The major dynamics of the gas turbine in combined cycle power plant(CCPP) include nonlinearities behavior, time delays, and uncertainties. Traditional control strategy could not offer satisfactory result. Using the linearization modeling technique, this paper deals with the velocity and power control by multivariable generalized predictive control method. Comparisons of generalized predictive control with conventional PID approaches were made under different load condition. Simulation results show the effectiveness of the proposed method.
