分段線性模型-
Based on the theory of piecewise - linear, the paper carries through the research of model self - adaptive control to electric arc - furnace electrode regulator system ( eafers ), and the digital self - adaptive control law of reference model is deduced. then, we designed the software simulation system of eafers according to the law, though which we studied the character of eafers. finally, a set of physical model of eafers, which is realized by hardware circuit, is designed according to the former research

該演算法首先利用導頻序列估計出當前ofdm符號間隔內通道線性變化的斜率和中間時刻通道的沖激響應值，然後根據線性模型利用估計出的參數得到當前符號間隔內所有時刻上的通道沖激響應。 -
In order to analytically deduce the characteristic scaling law, we have constructed a simplified piecewise linear model that describes the characteristic phenomenon so that we can quantitatively and analytically deduce the sudden change of the rules of the fractal dimension of the strange repeller and the averaged lifetime in the region occupied by the original attractor at a critical parameter value when the repeller disappears
為了解析地導出這種激變的特徵標度律，我們構造了一個描述這種特徵現象的簡化分段線性模型，並藉助它定量地解析描繪了當奇異排斥子在臨界參數值消失時，奇異排斥子的分數維和在原混沌吸引子區域迭代的平均生存時間的突變。 -

第三章（ pwm型dc dc變換器中分岔與混沌的研究）首先採用「逆向」分段數值模擬法對pwm型dc dc變換器中的倍周期分岔進行了理論分析與數值模擬；接著詳細地分析了適合於dc dc變換器非線性研究的數學模型一采樣數據模型，提出了dc dc變換器中存在環面分岔與鞍結分岔的可能性；最後通過電路實驗驗證了在電路參數發生變化時， dc dc變換器經歷一系列的倍周期分岔通向混沌的演化過程，並對混沌態下dc dc變換器的輸出特性進行了分析與小結。 -
An off - line algorithm of constrained model predictive control based on piecewise - linear feedback control law is presented to solve its potentially high on - line computational demand. the piecewise - linear feedback control law is off - line computed by lmi optimization problems and the on - line control computation reduces to the simple evaluation of the defined piecewise linear function, which makes the online computational efficiency significantly improved. 4
