Control system design for an autonomous helicopter model in hovering using pole placement method

This paper present the results of attitude, velocity, heave and yaw controller design for UTM autonomous model scaled helicopter using identified model of vehicle dynamic from parameterized state-space model proposed by Mettler (2000) with quasisteady attitude dynamic approximation (6 DOF model). Multivariable state-space control methodology such as pole placement was used to design the linear state-space feedback for the stabilization of helicopter because of its simple controller architecture. The design specification for controller design was selected according to Military Handling Qualities Specification ADS-33C. Results indicate that acceptable controller can be designed using pole placement method with quasi-steady attitude approximation and it has been shown that the controller design was complianced with design criteria of hover requirement in ADS-33C
