The microturbine is a complex thermal dynamic model. It is impossible to achieve accurate control because of its uncertainty and nonlinearity. In order to realize its steady control and fully exhibit its advantages among the distributed generation, the auto disturbance rejection control is introduced. Based on the input of rotational speed, extended-state observer is established. Also the controller uses the feedback to compensate and forms nonlinear algorithms to restrain state errors, which leads to optimize the microturbine's control. The paper presents the micro-turbine and the control strategy of ADRC in detail. Researches on how the ADRC improve the stability of the micro-turbine system are done via load disturbance and robust simulation. Simulation results show that the controller possesses good dynamic performance and stronger robustness.
