摘要
混沌控制是混沌运动在探险中的一个新的领域,而且它在混沌应用中是至关重要的。直到现在,许多不同的技术和方法已经被计划达成混沌控制,正如OGY方法、冲击的控制方法、微分几何学的方法和线性态反馈等等。时滞系统常在工程学、生物学、经济学和其他的学科中被遇到。在延伸的机器人稳定和控制理论研究方面,时滞控制系统引起了人们更新的兴趣。运用Razumikhin定理研究时滞混沌系统在标准反馈控制下的稳定性,得到了两条不依赖于时滞的稳定性判据。并通过实例验证了所得结果。
Chaos control is a new field in explorations of chaotic motions and it is crucial in applications of chaos.Until now,many different techniques and methods have been proposed to achieve chaos control,such as OGY method,impulsive control method,differential geometric method and linear state feedback,etc.Time-delay systems are frequently encountered in engineering,biology economy and other disciplines.In the wake of intensive research on robust stability and control theory.The stability and control of time-delay systems received renewed interests.The stability of time-delay chaotic systems via standard feedback control is studied,the approach of the study is based on Razumikhin Theorem.Two delay-independent stability criteria via SFC are derived.A numerical example is discussed to illustrate the advantage of the obtained results.
