 note = {This research was carried out as part of the study of the automatic landing system,and is concerned with a nonlinear simulation model of an aeronautical electric servo system.For the design of the multiplex servo system of the automatic landing system,the conventional first order lag model of the servo motor is unsatisfactory.Therefore,a more precise simulation model should be established.The model described in this paper was constructed in consideration of the nonlinearity of the servo motor (slip-torque characteristics).The procedure for parameter estimation of the slip-torque characteristics and the inertial moment of the rotor is presented.These parameters were estimated on the basis of the experimental data.The nonlinear model thus developed has been tested by digital simulation and compared with a conventional linear model.The simulation results show that the nonlinear model is suitable for the simulation of the servo system when the load applied to the servo motor varies with time.This condition occurs during the operation of the multiplex servo system of the automatic landing system., 資料番号: NALTM0300000, レポート番号: NAL TM-300},
