最小能量有限拍鲁棒控制系统的设计

本文采用2自由度控制器,以传递函数分式分解理论为基础,提出了一种在保证系统内部稳定和最佳鲁棒性前提下,实现最小能量控制的有限拍系统设计法。设计过程本质上是控制能量与响应时间的折衷。本文导出了折衷的最终界限,并给出了确定最佳响应时间的方法。

The Design of Robust Deadbeat Control Systems with Minimal Control Energy

By use of the transfer-function factorization approach, a new design method is proposed for robust deadbeat control systems with minimal control energy. This method uses the twodegree-of-freedom controller structure to realize the minimal-energy control under the condition of guaranteeing the internal stability and optimal robustness. The design procedure is essentially trade-offs between settling time and coorol energy. The bound of such trade-offs is derived and a method is given to select the most appropriate settling time.
