ABSTRACT:
A number N of AC machines, such as motors or generators, are independently controlled by a control system having 2N+1 phases, having N orthogonal sets of phase components. In a particular application, a hybrid vehicle including a generator and an induction motor are independently controlled by a five-phase controller having two independent sets of mutually orthogonal components. Each set of components controls one of the machines, and has no net effect on the other machine(s).
