Abstract :
This paper applies robust control techniques (RCTs) to the control law design of an unmanned air vehicle (UAV) which is modeled with parameter uncertainties. Firstly, physical modeling approach is used to develop a Linear Fraction Transformation (LFT) based model. Upon this, sensitivities of uncertain parameters are investigated. Then both H∞ and μ approaches are used to synthesize controllers and μ analysis is utilized to conduct robust analysis of stability and performance of the close-loop system. Finally, by comparing the results of different controllers, some conclusions are presented.
