中文摘要
      本文通过引入估计误差符号信息的反馈来建立一种新的鲁棒自适应控制器,能确保存在有界外部干扰时Lyapunov函数对时间的导数的半负定性,从而确保了系统的稳定性,使系统具有较强的鲁棒性.理论分析与仿真结果表明,该鲁棒自适应控制器对有界外部干扰有较强的抑制能力,并且可以加快自适应初始阶段的收敛速度.
英文摘要
      This paper proposes a new robust adaptive control scheme through introducingfeedback signal of the sign information of the estimate error. This scheme guarantees negative semidefinite of the time derivative of Lyapunov function with respect to bounded external disturbances,so it can assure stability and robustness in the presence of disturbances. Simulations show that the new shceme has strong ability to reject externaldistrubances and can improve the transient performance substantially.
