Abstract
PURPOSE: To use a proportional integral and differential operation control to control rapidly and stably the ventilator emission pressure to a fixed value throughout all ranges from a light load to a heavy load, by gain-compensating the operation output change value according to load change in the wind exposure quantity control of the drainage processing process, etc.
CONSTITUTION: Pressure change speed correction part 21 uses pressure value Pn at the current time dependent upon pressure detector 6, pressure value Pn-1 at the preceding sampling time, pressure value Pn-2 at the sampling time of the last but one, differential time TD, sampling time Δt, etc., to obtain pressure value Pn' at the current time which has the pressure change speed corrected, and this value Pn' is supplied to pressure deviation operation part 22. Operation part 22 subtracts pressure control target set value Psv from pressure value Pn' to obtain pressure deviation after differential correction. This pressure deviation en' is input to operation output change operation part 23, and there, pressure deviation en' at the current time, pressure deviation en-1' at the preceding time, integral time T1, proportional gain coefficient Kp, etc., are used to obtain current operation output change value ΔFn. This change value ΔFn is supplied to gain compensation operation part 24 to perform gain compensation accompanied with change of the load quantity.
