本發明係提供一種含有可調式時延補償的比例積分微分(PID)控制器(SP-PID),它利用一個簡單的調諧參數(Ksp),可將此控制器轉換成傳統 PID控制器或是Smith預測器。SP-PID控制器結合了兩種控制器的各項優點,本發明不但探討這新型控制器的特性,也提供控制器設計的步驟,並充分說明此控制器的強韌自由度。除此外,本發明對於處理程序模式誤差,可以有效的切換成傳統的PID控制器,有效的減少模式誤差對於控制器的影響。不過本發明最重要的工作,就是對於程序上現有的控制系統作改善,而不需加入額外的控制設備,直接利用所提出的控制方式改善控制效果。
In the present invention, a Smith predictor enhanced PID controller, SP-PID, is proposed. A tuning parameter Ksp is devised and the SP-PID controller would be gradually transformed from a PID controller to a Smith predictor as Ksp changes from 0 to 1. Properties of the SP-PID are explored and the design procedure is given to ensure a certain degree of robustness. Simulation results clearly indicate that the SP-PID takes advantage of the SP when 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 controller and its design procedure can be implemented in current process control computers with virtually no extra hardware cost.
