1. A control for a turbine engine system comprising a plurality of components including a multi-shaft turbine engine and one or more electrical machines coupled to the shafts of the turbine engine, the control comprising:

  • a vehicle manager;

    a constraint analyzer to determine applicable component limits based on current operating conditions of the turbine engine system, wherein each of the component limits defines an operating region in which, if the component limit is exceeded, the life or safety of the component may be compromised; and

    a limit management optimizer to generate a desired operating point and one or more possible operating points for the system based on the current operating conditions, the applicable component limits, and an optimization objective, wherein the one or more possible operating points each represents an objective trade-off involving a modification of the optimization objective to maintain the component limits or a modification of one or more of the component limits;

    wherein the limit management optimizer communicates data relating to the desired operating point and the possible operating points to the vehicle manager, and the vehicle manager selects the desired operating point or one of the possible operating points based on a trade-off between two or more of performance, efficiency, lifing, reliability, and stability;

    wherein the limit management optimizer communicates a control signal to one or more system controllers for the system to achieve the selected operating point, and wherein the one or more system controllers control the turbine engine system to achieve the selected operating point in response to the control signal.
