中文摘要 | 本文針對一般之自我調節程序,提出簡單實用之比例╱積分控制器調諧公式。 首 先建議利用 chen ( 1989, 1991 )所提之閉環反應曲線法建立一階常時延模式, G �d (s)=Ke . -ds/( τ s+1) 並依照各參數之相對大小將程序區分為落後支配,時延支配及極 小時延三類,再根據內模式控制原則公式推導適用之比例╱積分控制器參數值,所建議之調 諧公式為: 本文並舉出數個具典型特性之例子,說明本文所提方法的實用性。 |
英文摘要 | One simple tuning method for controlling self-regulating processes using the Proportional-Integral (PI) controllers is proposed in this article. The process dynamics are modeled as a first-order-plus-dead-time transfer function, G �d (s)=Ke . -ds/( τ s+1), by any existing identification method such as the closed-loop reaction-curve method of Chen (1989, 1991). The process dynamics would be classified into three categories: lag dominant, dead-time dominant, and small dead-time, according to the relative magnitude of time constant and dead-time in the model. The PI controller settings are then determined for each of these three process characteristics by using the Internal Model Control (IMC) principle. These proposed PI controller tuning rules are: Several numerical examples are given to demonstrate the effectiveness and the robustness of the proposed tuning method on a large class of self-regulating processes. |
