中文摘要 | 本文提出一種新的途徑來搜最適PID控制器的參數以達到二認成本最小化。吾人把實數的二次成本函數加以初數化,再利用最近提出的盒形空間對連續可微分複數對映之二維值域建造法來搜尋真正的最適PID控制器參數。由於文獻上已有效率佳的計算二次成本函數值及其梯度的參數演算法,且功能強大的個人電腦隨處可有,本文所提出的方法具有應用之前途。 |
英文摘要 | This paper presents a new approach to search for the optimal PID controller-parameters that minimize a quadratic cost functional. It is shown that by augmenting the real-valued quadratic cost functional into a complex-valued function, the recently proposed algorithm of constructing two-dimensional image of a box under a continuously differentiable complex-valued mapping can be applied to find the true optimal PID controller for a feedback control system. The proposed approach is promising because there exist efficient parametric algorithms for computing the quadratic cost functional and its gradients, and there are powerful personal computers for fast computation almost everywhere. |
