③ 摘要
設(shè)計(jì)要求一般用來描述應(yīng)該做什么以及應(yīng)該怎樣做。根據(jù)不同的應(yīng)用，設(shè)計(jì)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(cuò)）、瞬態(tài)響應(yīng)和頻率響應(yīng)等特性。除了這些一般特性外，在某些應(yīng)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(shù)變化敏感度的特性，在設(shè)計(jì)時(shí)也要加以考慮。
線性控制系統(tǒng)設(shè)計(jì)既可以采用時(shí)域方法也可以采用頻域方法。例如，階躍響應(yīng)、斜坡響應(yīng)或拋物線響應(yīng)下的穩(wěn)態(tài)精度這種時(shí)域特性在時(shí)域設(shè)計(jì)時(shí)比較容易滿足設(shè)計(jì)要求，單位階越響應(yīng)下的最大超調(diào)量，上升時(shí)間和調(diào)節(jié)時(shí)間也都適用于實(shí)時(shí)域設(shè)計(jì)。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(biāo)圖，相位-增益圖，Nichols圖表示，再運(yùn)用圖解法進(jìn)行研究，在頻域中比較容易滿足這些性能指標(biāo)

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.
