✦ Synopsis

An l1-optimal linear time-invariant (LTI) compensator may have an order signiΓΏcantly higher than that of the plant. In the state feedback case, there has been recent work exploring the use of nonlinear static feedback controllers which provide near optimal performance. In the case of D12 square and invertible, we show that it is enough to have the nonlinearity on a particular substate, which can be used to signiΓΏcantly simplify the design problem.

Consider a linear plant with a strictly proper rational transfer function and an input which is a known periodic waveform of unknown amplitude and phase. In the case when the periodic waveform has inΓΏnitely many non-zero harmonics, it is pointed out that for a wide class of linear, time-invariant (i
