Research on Aircraft Rudder Motor Servo Loading System

Servo loading system (SLS) is an important simulation system in hardware-in-loop flight simulation laboratory, which can simulate aerodynamic loads acting on the rudders of aircraft. To meet the demands to develop the current EHSLS (Electro-hydraulic servo loading system) into MSLS (Motor servo loading system) and to improve the systems performances, some basic technical problems about MSLS in theory and application are studied in this paper. First, the MSLS?s mathematical model is established. Then, digital simulation and analyses about the system are carried out. By analyzing the simulation results about the system, the conclusions are reached that adding of speed compensation and acceleration compensation in MSLS can further improve the systems performances to some extent so as to satisfy the requirements of applications.
