1. An apparatus configured to provide electrical converter control parameters, the apparatus comprising at least one processor; and at least one memory including computer program code; the at least one memory and the computer program code configured to, with the at least one processor, implement:
a structured H-infinity tuning module configured to determine one or more control parameters, for a model of an electrical converter control system and grid, based on variation of grid parameters, wherein the Structured H-infinity tuning module is configured to determine optimum control system performance by minimising an H-infinity norm, based on controlled variation of the grid parameters within ranges, wherein each range is a user-predetermined range for a corresponding one of the grid parameters, wherein the ranges are numerical ranges which specify allowable variation of the grid parameters and comprise endpoints between which the Structured H-infinity tuning module is operable to automatically vary the grid parameters; and
an output module configured to provide the one or more control parameters for implementation in the electrical converter control system.
