The Frequency Response Methods: Nyquist Diagrams
The nature of the input also influences thechoice of techniques to be used for system analysis and design. Many commandinput merely instruct a system to move from one steady-state condition to asecond steady-state condition. This type of input can be described adequatelyby suitable steps in position, velocity, and acceleration, and the Laplace domain is appropriate for this purpose. If,however, the interval between such step inputs is decreased so that the systemnever has time to reach the corresponding steady-state, the step representationand Laplace domain are no longer adequate. Such rapidly varying command inputs(or disturbance) may be periodic, random, or a combination thereof. The windloading of a tracking radar antenna, for example, results from a mean velocitycomponent that varies with time plus superimposed random gusts. If thefrequency distribution of these inputs can be calculated, measured, or evenestimated, the frequency response can be used to determine their effects uponthe system output.
From these equations we see that sinusoidalinput to a linear stable system produces a steady-state response that is alsosinusoidal, having the same frequency as the input but displaced through aphase angle Φ and having an amplitudethat may be different. This steady-state sinusoidal response is called thefrequency response of the system. Since the phase angle is the angle associatedwith the complex functionG(jω0) and the amplitude ratio （c0/r0） is the magnitude of G(jω0),knowledge of G(jω0) specifies thesteady-state input-output relationship in the frequency domain. G(jω0)is called the frequency transfer function and can be obtained from the transferfunction G(s) by replacing the Laplacevariable s by jω0 . Consequently, if G(jω0) can bedetermined from experimental data, G(s) can also be found by replacing jω0by s.

A. station automatic system design Abstract: with the reported GPS/GPRS bus based on GPS positioning, the bus status information (location, speed and so on) in real-time acquisition and analysis, when the vehicle reaches a predetermined position, realize the bus automatic station reporting function; through the GPRS network, bus status information to be transmitted to the bus monitor and dispatching center then, through the center of the operation of PC software, realize the monitoring and scheduling, bus information update function. The SD card storage information of a number of lines and MP3 audio files, easy to replace bus lines, at the same time player to achieve high quality speech information. Keywords: automatic newspaper station; GPS; GPRS; information update; monitoring and scheduling B. This paper describes the structure and the hardware of the servo system, especially to the previous position feedback four frequency multiplier circuit and a pulse counting circuit is improved, finally the experimental results show that, the system design is reasonable and can effectively avoid beating motor starting.

方法：频率响应的输入Nyquist diagramsthe自然也会影响技术可用于系统分析和设计的选择。许多commandinput仅仅是让系统从一个稳定状态转移到另一稳定状态。这种类型的输入可以被描述adequatelyby适当步骤的位置，速度，和加速度，和拉普拉斯域是适合这一目的。如果，然而，这样的步骤输入之间的间隔减小，systemnever有时间达到相应的稳态，步骤表示拉普拉斯域不再是足够的。这些快速变化的指令输入（或干扰）可能是周期性的，随机的，或它们的组合。例如某跟踪雷达天线，该windloading，从平均velocitycomponent随时间变化的结果加上叠加的随机阵风。如果这些输入的频率分布可以计算，测量，或evenestimated，频率响应可用于确定对系统输出的影响。从这些方程，我们看到，sinusoidalinput到线性稳定系统产生的稳态响应，alsosinusoidal，具有相同的频率作为输入，通过相位角Φ和流离失所一个amplitudethat可能不同。这种稳态正弦响应称为该系统的频率响应。由于相位角是与复杂的功能（Jω0）和振幅比（C0 / R0）的大小是G（Jω0），知识的G（Jω0）在频率域中指定的输入输出关系的稳定状态。G（Jω0）称为频率转移函数可以从传递函数G（s）获得通过更换laplacevariable S Jω0。因此，如果G（Jω0）可以通过实验数据，G（s）也可以通过更换ω0美国
