Closed loop speed control
Source: InternetPublisher:傻阿乐 Keywords: Generator MOSFET Updated: 2020/03/25
The DC motor- tachogenerator
closed-loop control uses the internal
error amplifier EA of UC3637 . The tachogenerator speed voltage signal is filtered and compared with the speed command
voltage, and the error is amplified and corrected as the control voltage n. AOUT
and B of UC3637. Ut supplies the H-bridge switching power amplifier, which is composed of four MOSFETs .
The system acceleration is approximately iOOr/min per millisecond. The 3dB bandwidth is 80Hz.
