摘　　要：为了验证伺服机构设计以及测试系统的正确性,提出并研制了伺服机构模拟器以及相应的动态测试系统;模拟器采用数字和模拟电路,能够模拟各种型号伺服机构工作特性;动态测试系统采用基于VXI总线测试模块以及虚拟测试软件完成对模拟器静态和动态参数的测试;通过对动态测试中的数字信号处理方法进行研究,提出了平滑滤波改进方法;测试结果表明,系统能够满足对伺服机构测试的需要;该系统可编程,操作简单,适合部队训练使用。In order to validate the correctness of the design of the servo and the test system, servo simulator and corresponding dynamical test system are developed. The servo simulator uses digital and analog circuit and it can simulate the characteristic of the servo. The dynamic test system uses VXf-bus test modules and virtual test software to complete the static and dynamic tests of the servo simulator. In research of the digital filter methods of the dynamic test, the improved flow filter method is brought forward . The test result indicates that the system meets the requirement of servo test. The servo is programmable, and the system is easy to use, so the system is suitable for training of the military.
