摘　　要：首先阐述了舵系统的工作特点和测控原理,针对其仿真测控过程中的精确定时需求,研究了Windows 2000系统下几种定时器的性能和用法,然后提出一种Windows高精度性能定时方法,在Visual C++6.0编程环境下,开发出一种高精度定时模块,该模块具备计时、三种延时等待功能接口;经试验测试,该模块定时精度可达μs级;最后将该定时模块应用于某舵系统的测试控制中,结果表明能较好地满足舵系统的测控应用的定时精度要求。Firstly, the work principle and characteristics of measurement and control of rudder system are narrated. For the issue of precision timing problem in the rudder system simulation measurement and control process, This paper discusses the performance and usage of several timers in windows system , then a high--precision timer method module was developed with Visual C＋＋ programme environment, the module Test verified that the precision of the timing module can reach microsecond. Finaly , its application in the rudder system measurement and control proved that the module can satisfy the timing precision application of rudder system simulation measurement and control.
