| 摘 要： | 分别采用连续域—离散化设计和直接离散域设计两种方法,设计某伺服系统的数字控制器以校正系统的性能.通过对比分析,可以得到各自的特点：连续域—离散化设计方法必须采用较小的采样周期,可以利用已积累了丰富经验的连续域设计技术;直接离散域设计避免了离散化误差,采样周期可以不必选得太小,但设计经验相对不足.

| Abstract: | Two digital controllers for a servo system are designed to correct system performance by means of continuous domain-discretization design and direct discrete domain design. The comparative analysis of the two design methods sums up the characteristics of each as follows ： continuous domain-discretization design must use a shorter sampling period and can make use of continuous domain techniques which have already accumulated rich experience ; direct discrete domain design can avoid the discretization error so the sampling period needn＇ t be too short, but it is relatively lack of experience. |
