Abstract:A new control scheme is proposed for aircraft engines, where the object is to transfer a regulated output (called main output) between two set-points, with the additional requirement that a set of outputs (called auxiliary outputs) remains within prescribed ranges. According to the prior outcomes, no assurance exists to protect output limits in transient regime by use of a traditional min-max scheme with linear compensators. To achieve a satisfied control performance for a corresponding output, each limitation loop is design separately. However, some auxiliary outputs still exceed their limits when other loop regulators are active or overshoot occurs. To overcome this problem, a linear matrix inequalities (LMI) approach is developed by considering the limit values in regulator design of other loops and the condition for no overshoot of auxiliary outputs. Finally, practical applicability is further demonstrated by numerical simulation. The results show that the designed controller can achieve a satisfactory dynamic and steady performance and keep the auxiliary outputs within constraints.
