Abstract :
A LQ optimal controller design with fuzzy gain-scheduler applied to nonlinear Bo105 helicopter flight control is presented. The stability theorem for the entire fuzzy nonlinear system with optimal feedback gain is proposed in this paper. The controllers for these linearized models are based on quadratic optimal technology. The Takagi-Sugeno (TS) fuzzy system is implemented as a gain-scheduler. The turning rate regulation and forward velocity tracking responses demonstrate the effectiveness of fuzzy gain scheduling.
