Backstepping adaptive control with MT-filter for time-varying systems

研究线性时变系统具有 MT-滤波器的反推自适应控制问题。给出了具有 MT-滤波器和σ修正自适应律的反推自适应控制器的设计 ,分析了闭环系统的稳定性和跟踪性能。同已有文献相比 ,难点在于误差系统的构造 ,并且稳定性的证明更加复杂。

For linear time-varying plants, the problem of backstepping adaptive control with MT-filter is studied. The design of the backstepping adaptive controller with MT-filter and δ-modified adaptive law is given. The analysis of both stability and tracking performance of closed-loop plant is discussed. Compared with the existing references, the difficulty of this work is the construction of the error plant, meanwhile the proof of stability is more complicated.
