Simulation test and analysis
In this experiment, the conventional controller, the
integral separated controller and the fuzzy self-adaptive
PIO controller are applied. And the corresponding
response curves are recorded and analyzed.
3.2.1 The response curves and analysis by the
three kinds of controllers for the step signal
The step signal test is done to prove the control
effects of the three kinds of controllers and the signal
value is 5.5 L/min. Fig. 5 shows the corresponding
response curves and Table 4 shows the analysis results.
From the curves and analysis results, the fluctuation
is lighter, the overshoot is smaller and the
adjusting time is shorter by the fuzzy self-adaptive
PIO controller than the ones by the first two kinds of
