摘要
采用无滞后控制系统与滞后控制系统的等价性方法,研究了多组多滞后区间系数中立型非线性时变控制系统的鲁棒镇定问题,给出了区间长度及时滞的估计范围,进而得到了系统渐近稳定的判定条件。此判据包涵了有关文献的结果,结论更具有一般性。
The robust stabilization problem of interval neutral type nonlinear time-varying systems with multi-group multi-delay is considered by using the equivalence method of control systems with delays and without delays. The sufficient condition of robust stability is obtained. At the same time, the estimate formulae of interval length limitation and time delay limitation are given. The criteria contain the existing results in the literature, and the conclusion is more universal.
