③ 摘要
設計要求一般用來描述應該做什么以及應該怎樣做。根據不同的應用，設計要求也各不相同，但通常包括相對穩(wěn)定性、穩(wěn)態(tài)精度（容錯）、瞬態(tài)響應和頻率響應等特性。除了這些一般特性外，在某些應用中往往還有一些特殊要求，如魯棒性或抗干擾性這種表示對參數變化敏感度的特性，在設計時也要加以考慮。
線性控制系統(tǒng)設計既可以采用時域方法也可以采用頻域方法。例如，階躍響應、斜坡響應或拋物線響應下的穩(wěn)態(tài)精度這種時域特性在時域設計時比較容易滿足設計要求，單位階越響應下的最大超調量，上升時間和調節(jié)時間也都適用于實時域設計。而增益裕量，相位裕量和諧振峰值M，這些衡量相對穩(wěn)定性的頻域特性，通常由Bode圖，極坐標圖，相位-增益圖，Nichols圖表示，再運用圖解法進行研究，在頻域中比較容易滿足這些性能指標

We often use design specifications to describe what the system should do and how it is done. These specifications are unique to each individual application, and often include specifications about relative stability, steady-state accuracy (error), transient-response, and frequency-response characteristics. In some applications there may be additional specifications on sensitivity to parameter variations, that is, robustness, or disturbance rejection.
The design of linear control systems can be carried out in either the time domain or the frequency domain. For instance, steady-state accuracy is often specified with respect to a step input, a tamp input, or a parabolic input, and the design to meet a certain requirement is more conveniently carried out in the time domain. Other specifications such as maximum overshoot, rise time, and settling time, are all defined for a unit-step input, and therefore are used specifically for time-domain design. We have learned that relative stability is also measured in terms of gain margin, phase margin, and Mr. These are typical frequency-domain specifications, which should be used in conjunction with such tools as Bode plot, polar plot, gain-phase plot, so and Nichols chart.
