Abstract:
In order to prevent the surplus torque existing in the electric load simulator ( ELS) for gun con-trol systems ( GCS) ,and further improve the control precision and dynamic characteristics of the output torque,the study on the output torque influences of the ELS is put forward. First of all,based on the struc-ture and working principle of the ELS system,a mathematical model was established,and the transfer function of output torque was obtained,with which influence factors were shown apparently. Then the con-nection stiffness,the input value of the torque motor,the angle of the position motor,friction,clearance and other nonlinear time-variant factors were studied in turn,and time-frequency and harmonic tracking methods were used to evaluate the system performance. At last,in combination with the results of simula-tion and experimental data,some qualitative and quantitative relationships of resulting in the harmonic dis-tortion of the output torque were studied,which provides strong theoretical support for improving the con-trol performance of the ELS.
