Converter Transient Energy Based Active Disturbance Rejection Control for Vienna Rectifier

In this paper, the Vienna rectifier inductors and capacitors total transient energy is utilized to implement active disturbance rejection control (ADRC), which can provide better dynamic and stability performances. The complete energy ADRC design procedure, including dynamic recovery time based feedback proportional gain calculation, stability based disturbance observer design, and model based control gain selection, are all considered in this paper. The same design method is also appliable to direct dc voltage ADRC control and dc voltage square ADRC control. Simulations results are provided to validate the effectiveness of converter energy ADRC. The superiority is illustrated by comparison results between converter energy ADRC control and traditional PI control.
