求解无差拍控制问题

确定以最小时间步长数使离散时间系统输出为零所需的控制输入：
Wolfram Language code: ss = StateSpaceModel[{(| | | | | - | - | -- | | 1 | 1 | -2 | | 0 | 1 | 1 | | 0 | 0 | 1 |), (| | | - | | 1 | | 0 | | 1 |), (| | | | | - | - | - | | 1 | 0 | 0 | | 0 | 1 | 0 | | 0 | 0 | 1 |)}, SamplingPeriod -> 0.1]; k = StateFeedbackGains[ss, {0, 0, 0}]
极点在原点，在三个时间步长内三阶系统的输出为零：
Wolfram Language code: ListPlot[OutputResponse[{SystemsModelStateFeedbackConnect[ss, k], {3, -1, 2}}, {0}, {t, 0.4}], Joined -> True, AxesOrigin -> {1, 0}, AxesLabel -> {"t"}]
