型号：IT94-3 HESG440310R2 HESG112699B

IT94-3 HESG440310R2 HESG112699B微分负反馈控制器是一种控制器，它的主要作用是改善系统的动态性能，但会降低系统的稳态精度。

IT94-3 HESG440310R2 HESG112699B微分负反馈控制器可以增大系统的阻尼比，从而使阶跃响应的超调量下降、系统平稳性增强、使系统调节时间加快。微分负反馈控制器还可以降低系统的稳态精度，为了减小稳态误差，必须加大原系统的开环增益。同时，微分负反馈控制器不影响系统的稳定性。

反馈调节和负反馈调节的区别如下：

性质不同 。IT94-3 HESG440310R2 HESG112699B反馈调节是系统本身的工作效果，反过来作为信息调节该系统的工作；负反馈调节是系统受到外界刺激后，产生的相应反应或结果，反过来又直接或间接地抑制或减弱最初发生变化的那种刺激所发生的变化。

作用不同 。IT94-3 HESG440310R2 HESG112699B反馈调节可以是正向的，也可以是负向的；负反馈调节的作用是纠正偏差，使系统输出量或状态量返回到它的目标值或给定值。

应用不同 。IT94-3 HESG440310R2 HESG112699B反馈调节可以应用于各种系统，包括生物系统、工程系统和社会系统等；负反馈调节在电子系统和控制系统中应用非常广泛，其作用是使电子系统或控制系统的输出返回到某种期望的状态。

The IT94-3 HESG440310R2 HESG112699B differential negative feedback controller is a controller whose main function is to improve the dynamic performance of the system, but to reduce the steady-state accuracy of the system.

The IT94-3 HESG440310R2 HESG112699B differential negative feedback controller can increase the damping ratio of the system, thus reducing the overshoot of the step response, enhancing the stationarity of the system, and speeding up the adjustment time of the system. The differential negative feedback controller can also reduce the steady-state accuracy of the system. In order to reduce the steady-state error, the open-loop gain of the original system must be increased. Meanwhile, the differential negative feedback controller does not affect the stability of the system.

The difference between feedback regulation and negative feedback regulation is as follows:

Different in nature. IT94-3 HESG440310R2 HESG112699B feedback adjustment is the working effect of the system itself, which in turn serves as the information adjustment of the work of the system; Negative feedback regulation is the corresponding response or result produced by the system after the external stimulus, which in turn directly or indirectly inhibits or weakens the change of the stimulus that originally changed.

The effect is different. IT94-3 HESG440310R2 HESG112699B feedback adjustment can be positive or negative; The function of negative feedback regulation is to correct the deviation so that the system output or state quantity returns to its target value or given value.

The application is different. IT94-3 HESG440310R2 HESG112699B feedback regulation can be applied to various systems, including biological systems, engineering systems and social systems. Negative feedback regulation is widely used in electronic system and control system, its function is to make the output of electronic system or control system return to a certain desired state.
