This paper presents the Scout B1-100 autonomous unmanned helicopter platform and an appropriate mathematical model for the hovering flight. The assembly of the experimental helicopter platform and its different hardware components are depicted. A dynamical model of the helicopter is derived from first principles and then linearized to obtain system description in state space. The model can be used...
Longitudinal channel dynamic equations of the experimental unmanned helicopter, Raptor-90, was established in hovering flight. The relationship between the power spectrum density and the system transfer function was described, and the way to derive formulas used to identify parameters of the single-input single-output, double-input single-output and three-input single-output linear time-invariant...
Identification experiments for small-scale helicopters are usually difficult to implement, and the data collected are to some extent non-informative and insufficient. This makes it impossible to identify a parametric model accurate enough for controller design. This paper presents a Bayesian method for identification modeling a small-scale helicopter. Priori physical knowledge is fully applied to...
