In this thesis, the research of light dynamic simulation and
control system design are discussed, and a remote control model
aircraft system is constructed to evaluate the design above.
First, an inverse flight dynamic algorithm is extract to
precisely predict the control input of a specified aircraft
trajectory. A panel code is used to calculate the aircraft
aerodynamic coefficients in order to construct the aircraft
flight dynamic equations. In addition, a block diagram of
aircraft flight control system includes the transfer function
specification of servo motor and gyroscope, the designs of
pitch attitude trajectory tracking and stability augmentation
system of neutral stable aircraft is constructed. Finally, an
analog circuit with the designs above and a data recording
system is implemented into the aircraft to fly. Analysis and
evaluation are conducted to improve the control system design.
