Multiple Rotating Integrator Controller for Active Filters
Author
Summary, in English
Abstract in Undetermined
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 dq-frame 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 harmonics to the measurement noise level.
