There are three ways to control and adjust the speed of the cooling fan. The introduction below can help you.
The speed adjustment of the DC cooling fan mainly depends on increasing the current of the coil, and the voltage can also be increased to increase the speed. But it is easy to burn the motor.
2. Use a DC speed regulator to control and adjust the speed.
3. DC torque motor speed control based on fuzzy PID.
Based on the analysis of the combination of fuzzy control and PID control, a two-dimensional fuzzy PID control algorithm is designed. The algorithm determines when to switch between fuzzy control and PID control according to whether the error signal reaches the threshold. Using encoder, 80196KC single-chip microcomputer , 16-bit D/A converter and DC torque motor combined with the above control algorithm to form a fuzzy PID steady-speed control system for DC torque motor.
Through the analysis and comparison of the measured data of standard PID and fuzzy PID
