Abstract :
Linear active disturbance rejection control (LADRC) method is investigated for the load frequency control (LFC) of power systems. Considering the model and the structure of the system, a second-order LADRC is adopted and the design procedure is introduced. It is found that LADRC is a model-independent control method with only two tuning parameters, thus it is very practical in industrial control. Simulation examples show that LADRC can damp the load disturbance very well but there are some limitations in the LADRC method.
