Figure 1: Water tank system
Consider a model of the water tank, which con-
sists of a rotary-pump, a tank, inflow and outflow
pipes and an output valve. The tank is filled with
the fluid by the rotary-pump. The fluid can drain
away from the tank through the output valve.
The system input is the voltage of the motor of
the rotary-pump
u [V] and the system output is
the level of the fluid in the tank
h [m].
The minimum and maximum of the input voltage
are
u
min
= 0 V, u
max
= 10 V. The height of
the tank is
0.3 m.

In the blocks in Figure 2 are filled variables Umin, Umax, b, ko and ho as an initial
condition of the integrator block 1/s.
