Using lifting techniques, a linear time-invariant state space model of multirate digital control systems is constructed at first. 首先利用提升技術(shù)，構造出多采樣率數字控制系統的線(xiàn)性時(shí)不變狀態(tài)空間模型。
Based on input-output data, state space models are directly identified by the SMI methods combined with the system theory, linear algebra and statistics. 這類(lèi)方法綜合了系統理論，線(xiàn)性代數和統計學(xué)三方面的思想，其特點(diǎn)是直接由輸入輸出數據辨識系統的狀態(tài)空間模型，因而非常適合多變量系統辨識。
