1. A model predictive control system a plurality of sensors indicating a current state of the system;

  • a desired trajectory generator for creating a desired dynamic response based upon commands;

    a model of plant dynamics starting with the current state of the system, a nonlinear programming module receiving the desired dynamic response and at least one system life goal and formulating a problem of achieving the desired dynamic response and the at least one system life goal for a window spanning one or more time steps as a solution to a nonlinear program problem using methods of model predictive control; and

    a nonlinear programming solver solving the nonlinear programming problem in each time step using an iterative algorithm based upon the model predictive control problem and a nonlinear programming algorithm.
