Small scale helicopter analysis and controller design for non-aggressive flights

A simplified analysis is presented for small scale unmanned helicopter controller design suitable for non-aggressive flight scenarios. A Matlab based detailed approach has been followed to analyze system mathematical characteristics, and provide the design process tool for PID/PD and fuzzy logic controllers for the yaw, pitch, roll (Euler angles) and the height variables for hover and slow flight. Both controllers have performed well; have demonstrated promising results being at the same time simple and mathematically sound.
