Abstract
This paper deals with positive- and negative-sequence current control of voltage-source converters. An enhanced weak-grid tolerant state-feedback controller design based on direct pole placement approach is proposed. The controller is synthesized from a body of literature on multi-frequency current control of grid converters. The resulting design yields consistent dynamic performance for varying grid strengths, and remains stable even under very weak grids. Due to the explicit parameterization of the pole locations, complex optimization methods often associated with robust control designs are avoided, which simplifies the controller design process.
