The application of asymptotic tracking and disturbance rejection in voltage source converter controller design

In this paper, the asymptotic tracking and disturbance rejection algorithm is revisited. It is applied in voltage source converter controller design to realize steady-state error when the reference is a sinusoidal signal. Detailed design procedures are also developed and described. Circuit level simulations are carried out, and results show the effectiveness of reference tracking and disturbance rejection. The robustness of this controller design is also demonstrated with several simulations.
