摘　　要：提出了用于产生混沌随机序列的ＤＳＰ（数字信号处理）混沌随机信号发生器构造算法。在吸引子转换技术的支持下，由该算法实现的混沌随机信号发生器之运转可避免伪周期及输出失谐的影响，因而其输出的混沌随机序列可用于计算机网络保密通信。Based on an I O model of interconnected continuous time plant with bounded disturbances,unmodelled dynamics and interconnections among subsystems,the analysis of robustness, convergence and global stability is given in detail.It proves that the proposed adaptive pole placement controller can guarantee globally asymptotical BIBO stability and the boundedness of all signals in the whole closed loop system. This control scheme has no restrictions on plant zeros but needs information exchange between subsystems. A sufficient stability condition of closed loop system is obtained.
