PID parameter setting
Thread Content
I would like to ask: for a constant-pressure water supply system where the pump motor has a power of 4KW and the pipeline pressure is maintained at 0.2MPA, how should the PID parameters of the frequency converter be set?
My experience: Setting the PID parameters of control valves requires practical application based on theoretical foundations. When there are problems, make sure to set aside some time to work on them for several hours; if anything needs to be stepped away from, either arrange for it to be manually activated at the appropriate time, or return it to its original settings before leaving.
The tuning of PID parameters is system-specific; there are no universal values, and it needs to be adjusted gradually in different systems.
PID parameters cannot be determined purely theoretically; they need to be obtained through practice, and are usually set during debugging
