英文摘要： By combining the adaptive control, backstepping design, optimization control and related mathematic theories, this project will investigate the adaptive optimization control problems for uncertain nonlinear systems based on the approximation property of the fuzzy logic systems or the neural networks. The main research contents of this project are as follows: 1) The adaptive optimization control problems for uncertain nonlinear triangular structure systems will be solved. The proposed adaptive optimization control schemes can overcome the restrictions of the system structure satisfying the matching condition in the existing optimization methods; 2) The adaptive optimization control design methods will be studied for uncertain nonlinear triangular structure systems with nonsmooth nonlinearity inputs. The proposed adaptive optimization algorithms can attenuate the effects of nonsmooth nonlinearity inputs; 3) The adaptive optimization control of uncertain nonlinear triangular structure systems with unknown control direction will be designed and the novel adaptive optimization strategies can be constructed based on Nussbaum gain technique. Finally, the stability, robustness and convergence of the closed-loop system and the other related theoritical problems will be proved and analyzed, and some high level theoritical research results will be obtained. The research of this project can further develop and enrich nonlinear control, intelligent control and optimization control theories. Moreover, it can provide some novel optimization control approaches for complex dynamic systems. Therefore, it has important theoretic meaning and academic values.
