In this talk, a limit management control arrangement using min-max logic is discussed. The min-max arrangement is commonly used in aeronautical gas turbine engines. The properties and shortcomings of the min-max logic are discussed and a new approach is proposed involving sliding mode controllers. The proposed control technique has guaranteed stability and does not introduce any conservativeness associated with constraint enforcement, representing a significant improvement over existing methods. The validity of the proposed technique is demonstrated with high-fidelity nonlinear engine simulations using NASA's CMAPSS package.
