Nonlinear PID control design for improving stability of micro-turbine systems

More and more attention has been paid on the Distributed Generation. The micro-turbine generation system is regarded as one of the most promising ways of Distributed Generation. The paper presents the model of the micro-turbine system and its control strategy. And the nonlinear PID control strategy is introduced in this paper to improve the stability of the micro-turbine system. The simulation comparison between classical PID controller and nonlinear PID controller has been performed. The simulation results demonstrate that the proposed nonlinear PID controller has better adaptability and robustness than the classical PID controller.
