Is it normal to have a large, large bandwidth for self-immunity control

Is it normal for the self-impedance control bandwidth to be large? However, it should be noted that too much bandwidth may result in a larger response to high frequency noise. Self-immunity controlActive Disturbance Rejection Control, ADRC, is a control method whose main task is to stabilize the system and improve its dynamic performance.

Bandwidth is an important concept in control research and affects the response speed of the system. Bandwidth is one of the parameters to be adjusted when debugging ADRC. If the bandwidth of the system is low, then the amplification factor for high-frequency noise is low and the system will not be greatly affected. However, a high bandwidth will not only respond to normal excitation signals at high frequencies, but will also have a larger response to noise in the same high frequency band.

So, although a large bandwidth can improve the response speed of the system, it may also bring noise problems. Therefore, the bandwidth needs to be reasonably adjusted according to the actual situation.
