By using scalar lyapunov function approach , sufficient conditions of stability are obtained 結(jié)合標(biāo)量lyapunov函數(shù)得到線性時變離散大系統(tǒng)穩(wěn)定性的充分條件。
Then a higher order lyapunov matrix equation can be transformed into some lower order matrix equations with unidirection coupling by using scalar lyapunov function approach 從而,利用標(biāo)量lyapunov函數(shù)將高階矩陣lyapunov方程化為若干個單向解耦的低階矩陣方程。
The scalar lyapunov function approach and vector lyapunov function approach of stability for large - scale systems are analyzed . and it is pointed out that the restriction of these approaches are only suited for large - scale systems with week coupling among subsystems 對大系統(tǒng)穩(wěn)定性的標(biāo)量lyapunov函數(shù)法和向量lyapunov函數(shù)法作了分析,指出這些方法只適用于子系統(tǒng)間具有弱耦合的大系統(tǒng)的局限性。
