摘　　要：针对一类不确定时滞混沌系统,基于Lyapunov稳定性理论,结合自适应控制方法,设计了自适应控制器及参数自适应律,证明了控制器和自适应律在参数不确定的情况下可实现时滞混沌系统的反同步,对不确定参数做出识别,并分析了控制调节器Ω的作用.数值仿真结果表明,该方法正确、有效.Based on Lyapunov stability theory and the adaptive control method,the adaptive controllers with corresponding parameter adaptive laws were designed for a class of delayed chaotic systems.The theory result proves that the designed controllers and adaptive law could achieve the anti-synchronization of delayed chaotic systems with uncertain parameters,identifying the uncertain parameters.Numerical simulations show that the method are correctness and effectiveness of the proposed method.Furthermore,we also analyzed the effect of control modulator Ω.
