ISA Transactions, Volume 98, March 2020, pp. 1-100019-0578https://doi.org/10.1016/j.isatra.2019.08.020https://dspace.lib.cranfield.ac.uk/handle/1826/15604This paper proposes a constraint-tolerant design with sliding mode strategy to improve the stability of aircraft engine control. To handle the difficulties associated with the high-frequency switching laws, merely attenuating the chattering is far from satisfactory. System constraints on input, output, and input rate should be addressed in the design process. For a sort of uncertain nonlinear systems subjected to the constraints, sliding mode regulators are designed using Lyapunov analysis. A turbofan engine is adopted for simulation, which shows that the methodology developed in this paper can handle the speed tracking and limit protection problem in a stable fashion, despite the negative influence posed by the system constraints.enAttribution-NonCommercial-NoDerivatives 4.0 Internationalhttp://creativecommons.org/licenses/by-nc-nd/4.0/Turbofan engineSystem uncertaintiesSystem constraintsSliding mode controlLimit protectionSpeed trackingAircraft engine controlArticle
