研究了采样系统L1最优控制问题中分段线性逼近的数学基础,其目标是最小化采样系统的L∞诱导范数。为了考虑样本间行为,我们首先考虑采样数据系统的提升表示。然后通过快速提升将采样间隔[0,h)划分为具有相等宽度的M个子间隔。最后,通过引入两种类型的“线性化算子”,用线性函数逼近每个子区间上的信号。这种方法被称为采样数据系统的分段线性逼近。利用预伴随算子的论证,证明了这种逼近方法为解决采样系统L1最优控制的分析与综合问题提供了理论基础.
This paper studies a mathematical basis of piecewise linear approximation in the L1 optimal control problem of sampled-data systems, which aims at minimizing the L∞induced norm of sampled-data systems. To take into account of intersample behavior, we first consider the lifted representation of sampled-data systems. The sampling interval [0, h) is then divided into M subintervals with an equal width by fast-lifting. Finally, the signals on each subinterval are approximated by linear functions through the introduction of two types of ‘linearizing operators.’ This method is called piecewise linear approximation of sampled-data systems. By using the arguments of preadjoint operators, we verify that this approximation techniques gives a theoretical basis for tackling the analysis and synthesis problems on the L1 optimal control of sampled-data systems.
