摘要
研究一类非线性奇异摄动系统的边界层鲁棒控制问题。该类系统边界层的不确定项不满足一般匹配条件。鲁棒控制器的设计分为伪名义边界层系统和整个边界层系统两步进行。在满足某些条件时,设计的控制器可使该类系统的边界层仍保持渐近稳定特性。将此方法用于中程空地导弹的中制导系统,仿真结果验证了该设计方法的有效性。
The systems are investigated. Uncertainties of boundary-layer of these systems do not statisfy the assumption of the standard matching conditions. The robust controllers are designed by two steps:ficti-tious nominal systems and the overall boundary -layer system. If some assumptions are satisfyed. the robust controllers designed here are locally (or globally) uniformly asymptotically stabilizing controllers of boundary - layer of these systems. This approach is used to design robust midcourse guidance law for a Air-to -Ground missiles. Simulation results indicate the effectiveness of this approach.
