一类机械振动系统的混沌控制

Chaos controlling of a kind of mechanical vibration systems

针对机械振动系统混沌运动的自身特点 ,提出了一种等效无源的混沌控制策略 .将原振动系统等效成无源非线性系统 ,利用无源系统的特性 ,对一类具有可动边界的机械振动系统的混沌行为施加控制 ,消除系统中的混沌运动 ,降低系统自激振动的危害 ,实现了系统的快速稳定 .

Aiming at the characters of nonlinearity chaos of mechanical vibration systems, a kind of strategy on passive equivalence controlling chaos is put forward.Using the characters of passive system, the chaos in the driving system of blooming mill can be eliminated, speediness stabilization of system is realized and the harm of self-excitation is reduced.
