The dual-rate control system, in which the sampling interval is an integer multiple of the holding interval, is designed using the null-space of the steady-state characteristic of the controlled plant. In the proposed method, a dual-rate control law is extended independent of the steady-state discrete-time output response. As a result, the intersample ripples caused by the input oscillation are eliminated by reallocating the control input. The proposed method based on the steady-state characteristic is a simple strategy compared with conventional methods based on the dynamic characteristic. © 2021 Institute of Electrical Engineers of Japan.

基于稳态双速率开环传递函数模型的无纹波设计

利用被控对象稳态特性的零空间设计采样间隔为保持间隔整数倍的双速率控制系统。在所提出的方法中，独立于稳态离散时间输出响应扩展了双速率控制律。因此，通过重新分配控制输入消除了由输入振荡引起的采样间纹波。与基于动态特性的传统方法相比，基于稳态特性的方法是一种简单的策略。© 2021 日本电气工程师学会。由 Wiley Periodicals LLC 出版。
