1. A method of controlling a hybrid power system comprising:
receiving state data for each of a plurality of energy devices coupled by drive linkages in the hybrid power system;
determining an energy demand of at least one of the plurality of energy devices based on the state data;
calculating a power system state vector based on the determined energy demand and on a stored data array defined by a hardware configuration of the hybrid power system;
producing a power request based on the power system state vector;
varying a flow of energy amongst the plurality of energy devices using at least one of the drive linkages based on the power request; and
the varying the flow of energy including varying a direction of the flow of energy between at least two of the plurality of energy devices;
wherein the stored data array includes an energy flow path matrix having a power supply axis and a power demand axis.
