Discrete-time controller and closed-loop transfer functions were developed for move suppressed lambda and the recently formulated m-shifted multiple-input-multiple-output (MIMO) dynamic matrix control (DMC). Using these transfer functions, robust analyses were conducted for MIMO plants by varying corresponding delay and gain ratios of the system. In all instances, robust plots indicate that the shifted DMC is less sensitive and hence more robust to variations in the plant parameters than move suppressed DMC. It was shown that the design of these MIMO DMC controllers depends on the plant closed-loop performance and overall stability, since the selection of lambda and m directly influences the plant robustness and closed-loop dynamics.
针对移动抑制λ以及最近提出的m移位多输入多输出（MIMO）动态矩阵控制（DMC），开发了离散时间控制器和闭环传递函数。利用这些传递函数，通过改变系统相应的延迟和增益比，对MIMO工厂进行了鲁棒性分析。在所有情况下，鲁棒性图表明，与移动抑制DMC相比，移位DMC对工厂参数变化的敏感性较低，因此更具鲁棒性。结果表明，这些MIMO DMC控制器的设计取决于工厂闭环性能和整体稳定性，因为λ和m的选择直接影响工厂的鲁棒性和闭环动态特性。
