Abstract:

For assurance airplane to land (or to warship) at request accuracy, it is very important for airspeed control system to have good control capability. Firstly, main function of airspeed control system was brief analyzed, and a few kinds structure schemes of airspeed control system were brief introduced. Secondly, airspeed control system structure principle diagram based on elevator bottom control and Simulink structure diagram were established. Using simulation method, simulation researches on the inside and outside control loops of the speed control system were done. Finally transmission ratio with good control performance corresponded speed control system was obtained. Simulation results showed that the designed control scheme of the airplane airspeed control system based on elevator control and the control laws were reasonable and feasible and good control performance.
