（ 6 ）認真研究了可拓控制，通過模擬算例對可拓控制與幾種神經網路控制進行了比較分析，得出了對慢時變非線性系統可拓控制比神經網路控制效果要好的結論。 -
Abstract : the theory of variable structure control of sing ular nonlinear control systems was considered based on the singular nonlinear systems itself by employing the method of geography, and gives the sufficient condition of existence of variable structure control and approximation theory of real sliding mode. it is shown that sliding condition only guarantee the slow - varying state of real sliding mode approach that of ideal sliding mode but not guarantee the fast - varying state of real sliding mode approach that of ideal sliding mode. the method applied for studying normal nonlinear system can not be used directely to singular nonlinear system
文摘:利用幾何方法，從廣義非線性系統本身出發，研究了廣義非線性控制系統的變結構控制理論，給出了系統存在變結構控制的充分條件及實際滑動模的近似定理.從所得結論可知，滑動條件僅能保證實際滑動模的慢變狀態趨近於理想滑動模的慢變狀態，而不能保證實際滑動模的快變狀態趨近於理想滑動模的快變狀態，研究正常非線性系統的方法已不能簡單地被利用到廣義非線性系統 -
