反馈和前馈控制系统之间的区别

1.反馈控制系统：
反馈控制系统基本上是一种控制系统，其中输出取决于生成的反馈信号。反馈控制系统负责处理反馈信号，该反馈信号进一步充当系统的输入。反馈控制系统由执行基本功能的不同组件组成，例如电阻器，晶体管和其他电器。反馈可以进一步分为正反馈和负反馈。

2.前馈控制系统：
前馈控制系统是将信号传递到某些外部负载的系统。在干扰影响控制变量之前，它先将其排除。它控制主要干扰，并多次与反馈系统结合使用。前馈系统对建模错误敏感。它可以直接测量系统中的干扰。

反馈和前馈控制系统之间的区别：

S.NO.	Feedback Control System	Feed Forward Control System
1.	In feedback system output depends on the generated feedback signal.	In feed forward system the signal is passed to some external load.
2.	Measure of disturbances in the system is not needed by feedback system.	Measure of disturbances in the system is needed by feedback system.
3.	All the disturbances are detected in feedback system.	All the disturbances are not detected in feedback system.
4.	The loop in a feedback system is a closed loop.	The loop in a feedback system is a open loop.
5.	It focuses on the output of the system.	It focuses on the input of the system.	6.	The variables are adjusted on the basis of errors.	The variables are adjusted on the basis of knowledge.
