Multivariable Sliding Mode Control Design for Aircraft Engines

Many control theories are used in controlling aircraft engines. However, the multivariable sliding mode control is not yet established in this application even though it has a lot of potential in dealing with complex and nonlinear systems such as aircraft engines. Therefore, a guideline in developing multivariable sliding mode control law for an aircraft engine is presented in this thesis. The problem of chattering in the sliding mode control is suppressed by the use of the boundary layer method. The control logic is tested by implementing NASA’s Commercial Modular Aero-Propulsion System Simulation 40k (C-MAPSS40k). Simulation results are analyzed and compared to the results obtained from the baseline controller. The robust property of multivariable sliding mode control is also examined by altering the flight condition of the engine.
