Abstract :
A kind of mixed LQR/ H∞ non-fragile controller with regional pole placement is designed for interval system model of flight kinematics system in this paper. H∞ performance, regional pole placement and robust guaranteed cost control of linear time invariant system are considered in this method and the existed conditions of the controller are deduction by linear matrix inequality (LMI) approach. Also, we consider the gain variation of controller due to parametric uncertainties and modeling errors which exist in fight kinematics system. Finally, simulation comparisons between non-fragile controller and traditional robust controller that without considering the gain variation of controller show the advantages and effectiveness of our approach.
