| Abstract |
A controller scheme based on multiple rotating integrators (MRI) for an active filter is presented,
analysed and evaluated. The inherent performance of integrators in the synchronous reference dqframe
for reduction of steady state errors are used in multiple rotating reference frames in order to
compensate harmonics to obtain a steady state error equal to zero. Both measurements and simulations
clearly verify the advantageous performance in comparison to presently used active filters. Particularly
in experimental verification, the MRI controller structure outperforms the alternative methods due to
its low sensitivity to parameter variation and non-linear properties of the system. This is particularly
important since the superiority of the MRI structure is not fully revealed only by simulation. It is
shown that the MRI structure do suppress the harmonics to the measurement noise level. |
