A control system for a multiphase-phase inverter system 10 comprises an electric current detection circuit 16 and a processor 14. Each phase of an electrical cycle is separated into a plurality of sections, inputs from the electric current detection circuit are received, each input indicating a measured phase current, and a phase current is calculated in each section. The phase current calculation in at least one of the sections is determined from a changing ratio of the value of the phase current calculated from the measured values of the other phase currents in the multiphase system and the measured value of the phase. The control system is particularly suitable for a multi-phase rotary machine, designed to control the rotation of a rotor of a multi-phase rotary machine based upon current in each phase. |
