控制系统振荡响应的问题有许多实际应用。本文研究无延迟LTI系统的闭环脉冲响应符号控制问题。如果一个稳定系统的脉冲响应不改变符号，那么它的阶跃响应既不会过冲也不会过冲。在本文中，我将证明这样的综合是可能的，如果开环系统没有真实的，非最小相位零。此外，我提供了一个稳定的补偿器，实现一个稳定的，非负的脉冲响应，如果存在的话。(C) 2002 Elsevier Science Ltd.版权所有。
The problem of controlling the oscillatory response of a system has many practical applications. In this paper, I consider the problem of controlling the sign of the closed loop impulse response for a delay-free LTI system. If the impulse response of a stable system does not change sign, then its step response will neither undershoot nor overshoot.In this paper, I will show that such a synthesis is possible iff the open loop system does not have real, non-minimum phase zeros. In addition, I provide a stable compensator that achieves a stable, non-negative impulse response, if there exists one. (C) 2002 Elsevier Science Ltd. All rights reserved.
