| Abstract |
Integral anti-windup is crucial for controlling converters subjected to constrains by the dc-link voltage.However, little literature is available about anti-windup if PR-controllers are applied. This paper presentsa new approach to tackle this problem by controlling damping of the resonator. Another aim is to analyzewhy one common anti-windup strategy for PI-controllers, that reduces the input of the integrator, alsoworks for PR-controllers. Even though the proposed damping anti-windup showed a somewhat lesserperformance than the conventional one, it ensured stability. The newly proposed strategy is inherentlystable and thus easy to tune. In particular, it is a reliable anti-windup for DSP-controlled converters. |
