摘要:
为了抑制炮控系统电动负载模拟器中存在的多余力矩,进一步提高其输出力矩的控制精确度和动态特性,对电动负载模拟器力矩输出的影响因素进行研究。首先结合电动负载模拟器系统的结构组成和工作原理,建立数学模型,得到输出力矩对应的传递函数和具体影响因素; 然后依次研究电动负载模拟器系统的连接刚度、力矩电机的输入力矩、负载电机的角度、摩擦、间隙等非线性时变量对系统力矩输出的影响,并分别采用时频阈分析和谐波跟踪等方法进行性能评估; 最后结合具体仿真和实验数据,分析影响力矩电机输出力矩谐波畸变的定性和定量关系,为提高电动负载模拟器控制性能提供有力的理论支撑。
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.
