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.
