Design, production and testing of education model "Helicopter with two rotors"

This work deals with designing and testing of education model "Helicopter with two rotors". The first part is focused on the consturction. Function requirement and set of options of solutions appointed. One of options is chosen and developed by 3D CAD systems. Balance-sheet of possible materials is elaborated in the maximum level available motor pull. Central placing of model is proposed to be able to move in 3 axes. The force electronic are designed and constructed in the second part. Suitable sensors, control method of motor speed and power support are chosen. According to this part the printed circuit board is created, which work as interface between PC (card MF624) and helicopter. In the last part model parameters are identificated and PID control is constructed. Selection procedure of parameters is analyzed in detail, each difficulties are mentioned and obtained data are evaluated. PID control is realized by degrees with regard to complexity of controlling the axes. Problems with disturbance and its impact on control is discussed also
