| 摘 要： | 分析了采样控制系统中稳态误差e_sr与采样周期T的关系。当采样开关后有零阶保持器时,e_sr与T无关;当采样开关后无零阶保持器且采样时间τ保持不变时,e_sr随T增大而增大。

The Relation between Steady State Error and Sampling Period in Sampling Control System |
| |
| Abstract: | The relation between steady state error e_(st) and sampling period Tin sampiing control system is analyzed. The Following conclusion is derived. If there is a zero-order holder behind sampling switch, e_(st) isn't related to T. However, if there isn't a zero-order holder behind sampling switch and sampling time keeps constant, then e_(st), increases acceding to the increase of sampling period T. |
