Research on Modeling and Simulation of Active Disturbance Rejection Controller for Gas Turbine

In this paper, a novel control approach is presented for a gas turbine. The approach is based on the active disturbance rejection concept, which can design an Active Disturbance Rejection Controller (ADRC) without an explicit mathematical model of the plant. The controller regards the friction and the coupling effects of several main subassemblies as the internal disturbance. And it can estimate and compensate the disturbances using the Extended State Observer (ESO) in the each sampling period. Hence ADRC is robust against the variations of plant. Using the parameters of turbine engine Titan 130 the simulation was developed. Through the results of simulation, it is verified that the proposed approach is superior to the classical PID regulator in maintaining the stability.
