Nonlinear Feedback Speed Control of Internal Combustion Engines

In this paper, the engine speed control problem formulation is motivated from realistic engineering performance requirements and practical implementation considerations. For an actual internal combustion (IC) engine, based on Lyapunov theory, two simple nonlinear feedback controllers are constructed by using engine system physical characteristics to ensure system stability, and then, the extension for the basic idea using switching boost action is developed to improve system response ability, and the benefit is also discussed from analytical point of view. Experimental results are given to verify the performance of the proposed strategies.
