5.5.15 PID control
PID control, a common mode for process control, is mainly used to adjust the inverter output
frequency or output voltage by performing scale-division, integral and differential operations on the
difference between feedback signal of controlled variables and signal of the target, thus forming a
negative feedback system to keep the controlled variables above the target. It is applicable to flow
control, pressure control, temperature control, and so on. The following is the basic schematic block
