    "System identification"(系統辨識)是控制工程、信號處理和相關領域的核心概念,指通過實驗數據建立系統數學模型的過程。以下是詳細解釋:

    1. 定義
      系統辨識是通過觀測系統的輸入輸出數據,構建數學模型來描述系統動态特性的方法。其目标是找到最能匹配實際行為的數學表達式,如微分方程、傳遞函數或狀态空間模型。

    2. 應用場景

      • 工業過程控制(如化工反應器建模)
      • 機器人動态特性分析
      • 航空航天系統設計(飛行器氣動力建模)
      • 生物醫學工程(生理系統建模)
    3. 基本步驟
      ①數據采集:記錄系統在特定輸入(如階躍信號、隨機噪聲)下的響應;
      ②模型結構選擇:根據先驗知識選擇模型類型(如ARX、狀态空間);
      ③參數估計:用最小二乘法、最大似然估計等方法确定模型參數;
      ④驗證:通過新數據集檢驗模型預測能力。

    4. 數學表示示例
      線性時不變系統的差分方程模型:
      $$ y(t) + a_1y(t-1) + cdots + a_ny(t-n) = b_1u(t-1) + cdots + b_mu(t-m) $$ 其中$u$為輸入,$y$為輸出,$a_i,b_j$為待辨識參數。

    5. 工具與挑戰
      常用工具包括MATLAB System Identification Toolbox和Python SciPy。主要挑戰包括噪聲幹擾、非線性特性處理及模型複雜度權衡。

    系統辨識對控制器設計、故障診斷和系統優化至關重要,是連接理論與實際工程應用的橋梁。
