The adaptive control issue of a class of linear time-varying systems with uniformly bounded but piecewise Lipschitz continuous parameters is considered. 考虑一类参数一致有界、分段Lipschitz连续的线性时变系统的自适应控制问题。
It is well known that if a bounded domain Ω has a locally Lipschitz boundary then C ~ ∞ (■) is dense in W ~ ( m, p )(Ω). 当有界域Ω有局部Lipschitz边界时,C~∞(■)在W~(m,p)(Ω)中的稠密性是众所周知的。
