中文摘要 | 本篇提出了一個新型的史密斯預測器;SP-PID 控制架構;藉由調諧參敷Ksp從0至1的範圍內的設定,可以很容易地將原本的史密斯預測器傳統PID控制架構做漸近式切換。由模擬的結果發現,本SP-PID控制在模式誤差很小的情況下,可以保有了原本史密斯預測器的良好控制效果,然而在有模式誤差的情況下也能確保有相當程度上的強韌性。在實際使用上也相當容易,使用者可依據模式的優劣將SP-PID做適當的調諧,而調諧的方式只需簡單將Ksp做適當設定即可。因此本控制架構可以很容易在現今電腦控制程序上應用,且不需花費其他硬體成本。 |
英文摘要 | In this work, a Smith predictor enhanced PID controller, the SP-PID, is pro-posed. A tuning parameter Ksp is devised which gradually transforms the controller from a PID controller into a Smith predictor as Ksp changes from 0 to 1. The Properties of the SP-PID are explored and the design procedure is to ensure a certain degree of robustness. Simulation results clearly indicate that the SP-PID takes advantage of the SP when a small modeling error is encountered and it is gradually detuned to a PID controller, a user friendly controller, when the model quality degrades. Moreover, the proposed concept can be implemented to current process control computers with virtually no extra hardware cost. |
