Robust control of UAVs using H∞ control paradigm

In recent past, the use of Unmanned Aerial Vehicles (UAVs) has been progressively regnant and significant in several applications related to civil as well as military purposes. Due to their numerous benefits, the control and dynamic modeling of UAVs are becoming the attractive field of research. Considering all these facts, this paper has present the conventional inner-outer loop strategy with some proposed modifications and a robust controller is designed for the inner control loop. Due to uncertain nature of aircraft, Robust H

Loop Shaping Design Procedure (LSDP) is used to synthesis the controller. The designed inner loop controller is applied to the system and the simulation results indicate the good performance and robustness margins of the designed controller against the parameter uncertainties.
