In this paper, we propose a model-based control system design for autonomous flight and guidance control of a small-scale unmanned helicopter. Small-scale unmanned helicopters have been studied by way of fuzzy and neural network theory, but control that is not based on a model fails to yield good stabilization performance. For this reason, we design a mathematical model and a model-based controller for a small-scale unmanned helicopter system. In order to realize a fully autonomous small-scale unmanned helicopter, we have designed a MIMO attitude controller and a trajectory controller equipped with a Kalman filter-based LQI for a small-scale unmanned helicopter. The design of the trajectory controller takes into consideration the characteristics of attitude closed-loop dynamics. Simulations and experiments have shown that the proposed scheme for attitude control and position control is very useful.

Field survey provides data for further research and is a key link in research on traditional settlements and other architectural heritage. However, due to the complexity of the landform, layout, orientation of buildings, forms and structures of traditional settlements, mapping and other fieldwork may take much time and efforts and are very difficult. Besides, satellite remote sensing data are few. Therefore it is necessary to introduce some advanced equipment and technology for spatial information acquisition. Through years of experiments with aerial and ground-based equipments, the author finds that small unmanned helicopter, with its multi-functional spatial information acquisition capacity, is the best choice for the research of traditional settlements and other related fields.
