For the next generation of manufacturing, represented by Industrie 4.0, a multi-input controller is designed directly from controlled data, without using the mathematical plant model, where the ratio between the D/A conversion of multiple inputs and the A/D conversion of a single output is non-uniquely. With the proposed method, the fixed-structured controller is optimally designed by solving a model reference problem using one-shot data. Furthermore, to eliminate inter-sample ripples emerged by input oscillation, the deviation of the control inputs is also evaluated using the proposed method. As a result, a non-ripple data-driven controller is achieved. Numerical examples show that the proposed multi-rate data-driven method is superior than the conventional single-rate method.

对于以工业 4.0 为代表的下一代制造业，多输入控制器直接从受控数据设计，不使用数学工厂模型，其中多输入的 D/A 转换与 A/D 转换之间的比率单个输出是非唯一的。使用所提出的方法，通过使用一次性数据解决模型参考问题来优化设计固定结构控制器。此外，为了消除输入振荡出现的样本间波纹，还使用所提出的方法评估了控制输入的偏差。结果，实现了非波纹数据驱动的控制器。数值例子表明，所提出的多速率数据驱动方法优于传统的单速率方法。
