Abstract:
This study investigates the control of liquid level of flow control system
Proportional-integral-derivative controllers were used in this study as a
control strategy. Optimum control setting has been determined and
implemented by using Ziegler-Nicholls tuning method. Fuzzy logic control
systems were introduced by (Lotfi Zadeh) to optimize the process control
parameters in better way. In this thesis, a flow control system strategy been
implemented with proportional-integral-derivative controller and then
optimized with fuzzy logic controller (Mamdani-type fuzzy processing). The
fuzzy logic control strategy shows the improvement in control specification
like maximum overshoot, steady state error compared with PID control
strategy.
The results show the superiority of fuzzy logic controller over comparing
with proportional integral derivative controller.
