How is a seamless manual-to-automatic switch achieved?

When driving for the first time, being able to avoid disturbances depends entirely on experience. Because some set values and PID parameters are initially based on empirical values. It must be rather unstable. Then, once the device has been manually adjusted to a relatively stable state and the actual parameters on site are close to both the set values and the automatic set values, switch to automatic mode, and then gradually adjust the PID parameters one by one. Next is simple adjustment; the knowledge required is what is learned in universities regarding PID parameter tuning, as well as the methods for tuning PID parameters taught by experienced professionals – there’s nothing complicated about it. As a meter technician, I can’t provide the original poster with more detailed information, as I only know the methods involved; the specifics of adjustments need to be figured out gradually by the technicians. For devices that are operating well, the process must be superior to that of instrument operation.
