The invention relates to a PID (
Proportion Integration Differentiation) control-based output regulation method and
system for an activation
coal feeder of an European
silo, and solves the problems that the manual output regulation stability is poor and the operation depends on experience in the prior art. According to the method, the target
coal flow is preset to serve as reference input, the electronic scale is used for collecting the actual flow in real time, deviation is calculated, the controlled quantity is generated through proportional, integral and differential adjustment of the
PID controller, the air pressure of an oscillation motor of the
activated coal feeder is automatically adjusted, and the closed-
loop control process of measurement, deviation calculation and automatic adjustment is formed. The
system comprises a
target setting unit, a flow acquisition unit, a PID
control unit and an
execution unit. According to the method, the
working pressure of operators can be reduced, the
coal flow control precision and the
bunker adding process stability can be improved, the
bunker adding amount and time can be accurately estimated,
technical support is provided for a subsequent automatic
bunker adding
system, and the method has the advantages of economy and intelligence.
