摘　　要：本文通过引入一类新的目标函数,对死区非线性系统建立了全局收敛的自适应控制算法,该算法可用于最小相位和非最小相位系统,并具有渐近最优的控制效果,仿真实验表明本文算法具有良好的动态性能。In this paper, globally convergent adaptive control algorithms are presented for linear systems with dead-zone nonlinearity. These algorithms, which can be used to control the nonminimum phase systems, will ensure that the system input and output are sample mean-square bounded and achieve asymptotically the optimal control with the system parameters known. The results of simulation show that the algorithms are of good. performance.
