Pressure parameter.The concept of PID valve 8: the adjuster control law being most widely used is ratio, integral, differential control, abbreviation
PID control, also known as PID are adjusted.PID controller has last 100 years history as earliest practical controller, is currently still
Most widely used industrial control unit (ICU).PID controller is easily understood, and the prerequisites such as accurate system model are not required in use,
Thus become the controller being most widely used.PID controller is made of proportional unit P, integral unit I and differentiation element D,
The PID adjusting of valve is one kind that industry control PID is adjusted.PID controller is one and common in Industry Control Application feeds back to
Circuit unit is made of proportional unit P, integral unit I and differentiation element D.The basis of PID control is ratio control；Integration control
Steady-state error can be eliminated, but overshoot can be can increase；Differential control can accelerate Great inertia system response speed and weaken overshoot to become
Gesture.This PID valve container 4, visual agitating paddle reaction kettle 1 compared with are connected to, and PID valve accesses computer, and visual agitating paddle is anti-
It answers the volume compared with of kettle 1 to carry out closed-loop control, steady-state error is eliminated by PID, reaches accurate control.PID pressure control module
In experiment, pressure reduction in visual agitating paddle reaction kettle 1, by comparing closed-loop control from comparing container to visual agitating paddle
Make-up gas in reaction kettle 1, until the pressure in visual agitating paddle reaction kettle 1 reaches setting pressure, visual agitating paddle reaction kettle 1
In hypertonia, by feedback signal, so that discharging gas in visual agitating paddle reaction kettle 1 into pressure vessel makes pressure
It reduces.To reach setting pressure, setting in this way is so that the intracorporal pressure of kettle is kept constant.
