Optimal Control of Gas Turbine Engines Using Mathematical Programming
In previous chapters, different types of mathematical models of aero engines were described along with methods for their creation and estimation. Also, some application areas were considered, which included conventional engine control, controller testing and engine condition monitoring. In this chapter, mathematical models of aero engines are applied to design of optimal control. Within this approach two main issues are considered: optimal control laws based on static engine modelling and optimal control algorithms making the engine follow program trajectories with maximum accuracy. The last is based upon engine dynamic modelling. Optimal control is presented as a mathematical programming problem, which consists of an objective function, equality constraints, and inequality constraints . Examples illustrate implementation of the proposed approach to solving various optimization problems in aero engine control.
