Design of micro-turbine disturbance rejection controller design and verification method

In order to shorten the design cycle of the micro-turbine controller and verify the performances before actual test, micro-turbine controller design and verification methodology were proposed. Considering the main inertia of the micro-turbine control system gets the small perturbation transfer function model of the steady-state operating point, dynamic model similarity between micro-turbine control system was used and induction motor speed control system the simulation system of micro-turbine was given. Two controllers were designed and the performances were compared based on the simulation system. For resolving problems of high speed volatility and long dynamic adjustment time in the actual system, the load feedforward control was proposed. Simulated and experimental results prove that the new micro-turbine controller design and verification method are feasible and effective, and the load feedforward control is validated to enhance the performance of resisting disturbance greatly.
