“…Only a few examples of system identification techniques applied to small-scale helicopters exist in the literature, and the results are not as good as in the case of fullscale helicopters. 16,[21][22][23] Under the assumption that, in hovering, a multivariable helicopter system can be considered as four independent SISO systems, time-domain system identification theory can be used.…”

This paper presents the identification of a miniature coaxial helicopter system. First, the helicopter flying principles are described and the hardware setup of the developed platform is presented. Further, linear models are developed for the movements of the helicopter using prediction error identification methods. The results in this case are accurate and can be used for performant controller design in some operating points. But in order to model the complete dynamics of the helicopter, nonlinear models are developed using recurrent dynamic neural networks. In this case the models obtained present a higher accuracy compared with the linear case and also with the results published until now. In the end, the advantages of nonlinear modeling based on neural networks is emphasized and some conclusions are drawn.

“…PID, robust control, and intelligent control methods have been proposed for SUAR system [6][7][8][9][10][11][12]. Due to its simple structure, PID control method is often used in SUAR systems [13,14]. However, PID control has little robustness to environment disturbances.…”

As a complex system, the control performance of small unmanned aerial rotorcraft is easily affected by the dynamic model errors, measurement errors, and environment disturbances. This paper proposes a disturbance observer based control method to improve performance. The disturbance observer based control is constructed by the feedback control and a series of integral filters. The system stability can be guaranteed by the feedback control method. Furthermore, the disturbances can be estimated and eliminated quickly by the integral filters. Therefore, the control performance can be improved effectively. The control performance of the disturbance observer based control has been validated by a series of flight tests. Compared with feedback control, the disturbance observer based control yields a better tracking performance in the presence of disturbances.
