Abstract
PURPOSE: To reduce the switching operation of a motor valve and minimize the fluctuation of a flowing-in water quantity by selecting a method, by which the valve opening variation output is calculated, according to the state segment of a pond level and controlling the pond level.
CONSTITUTION: On a basis of pond level deviation ln at a current sampling time and pond level deviation ln-1 at the preceding sampling time, proportional term Kp(ln-ln-1) and integral term K1ln are calculated. The state of a pond level is divided into state segment 1 where the pond level is over an upper limit value and is rising or the pond level is below a lower limit value and dropping, state segment 2 where the pond level is between the upper limit value and an object value and is rising or the pond level is between the lower limit value and the object value and is dropping, and state segment 3 where the pond level is not in segment 1 and segment 2. Kp+K1ln, Kp, and 0 are processed as the operation result for segments 1, 2 and 3 respectively. The operation result is given to integrating operator 6 as control output Δϕn.
