摘　　要：对微机控制系统的采样周期进行了研究 ,以一典型控制系统为例 ,从理论上分析了采样周期对系统的稳定性、动态品质、抗干扰能力及数字PID控制作用的影响 ,并指出过小的采样周期会使最小相位系统的性质发生改变。The sampling period of the microcomputer control system is studied. Based on a typical control system, the influences of sampling period on the system are analyzed theoretically, such as the stability, the dynamic quality, the anti-jamming capability, and the digital PID controller. The conclusion is revealed that sampling period can change the characteristics of the minimum phase system.
