Abstract Inversion-based feedforward control is a basic method of tracking controls. The aim of this paper is to design MIMO multirate feedforward controller that improves continuous-time tracking performance in MIMO LTI systems considering not only on-sample but also intersample behavior. Several types of MIMO multirate feedforward controllers are designed and evaluated in terms of the 2-norm of the control inputs. The approach is compared with a conventional MIMO single-rate feedforward controller in simulations. The approach improves the intersample behavior through the optimal selection of input multiplicities with MIMO multirate system inversion.

具有输入多重性选择和样本间行为分析的 MIMO 多速率前馈控制器设计

摘要 基于反演的前馈控制是跟踪控制的一种基本方法。本文的目的是设计 MIMO 多速率前馈控制器,以提高 MIMO LTI 系统中的连续时间跟踪性能,不仅考虑样本上的行为,还考虑样本间的行为。根据控制输入的 2 范数设计和评估了几种类型的 MIMO 多速率前馈控制器。在仿真中将该方法与传统的 MIMO 单速率前馈控制器进行了比较。该方法通过优化选择具有 MIMO 多速率系统反演的输入多重性来改善样本间行为。
