Abstract :
Aimed at the rotor speed unmeasured, this paper presents a speed sensorless control strategy with observer for permanent magnet wind turbine generator based on port-controlled Hamiltonian (PCH) model. The PCH model is established by taking full advantage of the physics structure of wind turbine system and then the full-order observer is proposed based the PCH model to estimate rotor speed. This structure of controller is simple but also reflecting physical meaning. Moreover, an adaptive controller is investigated under the uncertain parameters and the external disturbance. The proposed strategy is proved valid by the simulation illustration.
