Item Adaptive Backstepping Interval Type-2 Fuzzy Neural Network Controller Design for Nonaffine Nonlinear Systems(2009-12-19) C.-K. Chen; W.-Y. Wang; Y.-G. LeuItem Compact Ant Colony Optimization Algorithm Based Fuzzy Neural Network Backstepping Controller for MIMO Nonlinear Systems(2010-07-03) W.-Y. Wang; C.-K. Chen; Y.-G. Leu; C.-Y. ChenIn this paper, a compact ant colony algorithm used to tune parameters of fuzzy-neural networks is proposed for function approximation and adaptive control of nonlinear systems. In adaptive control procedure for nonlinear systems, weights of the fuzzy neural controller are online adjusted by the compact ant algorithm in order to generate appropriate control input. For the purpose of evaluating the stability of the closed-loop systems, an energy fitness function is used in the ant algorithm. Finally, a computer simulation example demonstrates the feasibility and effectiveness of the proposed method.
