摘　　要：本文通过引入一个非线性补偿环节和一个开关量函数,解决了滞环非线性系统的自适应控制问题,并分别对滞环宽度已知和未知情况,建立了大范围渐近收敛和稳定的加权自适应控制算法.这种算法具有渐近最优的控制效果,能用于非最小相位系统.仿真结果表明,该算法具有良好的动态性能.In this paper, the weighted adaptive control algorithms are presented for linear dynamic systems with nonlinearity of the type of backlash with known or unknown width. The global convergency and stability of the algorithms have been established. The algorithms can be applied to the control of stable and some unstable nonminimum phase linear systems having backlash nonlinearity. The results of simulation are also provided.
