根据三容水箱对象本身的特性,采用带遗忘因子的辅助变量最小二乘法对其CARIMA模型参数进行了辨识,并基于辨识所得的参数模型,用广义预测控制方法对三容水箱的液位进行了控制。实验结果表明,采用此CARIMA模型的广义预测控制算法有良好的控制效果。与PID控制相比,缩短了调整时间,抑制了超调量。
根據三容水箱對象本身的特性,採用帶遺忘因子的輔助變量最小二乘法對其CARIMA模型參數進行瞭辨識,併基于辨識所得的參數模型,用廣義預測控製方法對三容水箱的液位進行瞭控製。實驗結果錶明,採用此CARIMA模型的廣義預測控製算法有良好的控製效果。與PID控製相比,縮短瞭調整時間,抑製瞭超調量。

Based on the characteristics of three-tank water, the parameters of its CARIMA model are identified by reeursive instrumental variable least squares with forgetting factor method. An experiment taking the three- tank system as the controlled objects with Generalized Predictive Control (GPC) based on the CARIMA model is carried out. The experimental results indicate that the Generalized Predictive Control algorithm, compared with PID, has good control performance in reducing settling time and restricting the overshoot.
