英文摘要： Nonlinear homogeneous system theory has been effectively utilized in the analysis and synthesis for nonlinear systems, and has already obtained numerous results. Deeper research into the nonlinear homogeneous system theory will further develop and improve the nonlinear control theory. This project will study the robust control, active anti-disturbance, time-optimization problems for a class of complex nonlinear uncertain systems and hence extend the controllable nonlinear system ranges. . The main contents of this project are as follows: (1)With the objective of designing implementable sampled-data controller, a systematic non-smooth sampled-data control law will be proposed for a class of inherently nonlinear p-norm systems and then a homogeneous sampled-data control law for a class of homogeneous approximation systems. (2)With the objective of designing active anti-disturbance controllers for a class of nonlinear homogeneous approximation uncertainty systems subject to disturbances, an effective disturbance rejection control law will be developed. (3)The theoretic results will also be utilized into the uncertainty/disturbance attenuation problem for real-life plants such as power electronics converters, mini quad-rotor, hypersonic vehicle, etc. . This project will further develop the homogeneous control theory for nonlinear systems, and facilitate the implementation of advanced nonlinear control methods into practical industrial systems for the objective of controlled performance improvement, hence will cause direct or indirect economic benefits.
