A current signal (I ) representative of the actual current drawn by the load(s) ( ) is provided. The greater of the demand signal (M ) and the current signal (I ) is selected ( ) and utilized to provide a control signal (Mx, Mx′, Mx″) for regulating one or more of the reactants and coolant ( ). One or more status signals (Xp, Xp′, Xp″, Vap) indicative of the status of a regulated one of more of the reactant/coolant and/or a respective operating process effected, is provided. Each status signal is transformed to a respective load capability signal ( ). The lesser of the demand signal (M ) and each of the load capability signals ( ) is selected ( ) to provide an output signal (M ) for commensurately controlling a system load ( ).
