Abstract
PURPOSE: To reduce the opening and closing motions of motor valves and to minimize the variation of flowing water amount, by sectioning the state of pond water level and selecting the calculation method of valve opening increment output according to the section into control.
CONSTITUTION: The pond water level L of the reservoir 1 is in A/D conversion with the converter 4, and the digital signal is sampled 20 every given period and fed to the control unit 5-2. The input section 11 of the unit 5-2 outputs the pond water level objective R preset and the deviation ln of the pond water level sampled at present and it is inputted to the control section 16, P operation section 13, and I operation section 14. Based on the deviation ln, a given value dL of variation rate of pond water level preset at the control section 16, and pond water level deviation ln-1 at sampling before from the memory section 12, the state of the pond water level L is sectioned into four. The control section 16 inputs the rate term to ln-ln-1 from the operation section 13 and the integration term to ln from the operation section 14 to operate the state of four sections of the pond water level. The valve opening increment Δϕn is outputted to the integration operation unit 8 to reduce the opening and closing motions of motor valve and to minimize the variation of flowing water amount.
