Experimental H-infinity robust control of aerial vehicle flight

This paper proposes and evaluates the comparative studies between the classical controllers (PI, PD and PID) with H∞ robust control technique for an 3-DOF helicopter. The control algorithm uses a robust controllers synthesized by the H∞ loop shaping approach. The experimental results show that the robust controllers stabilize the system and reject the disturbances when the system is subjected to uncertainties of a norm lower than the maximum stability margin.
