Abstract :
A real-time control of liquid level in a conical tank is studied. System identification of this nonlinear process and tuning of the fuzzy system are undertaken. Genetic algorithms are used to tune the membership functions of the fuzzy system. The results of the tuned fuzzy controller are compared to a proportional integral controller to evaluate the performance of the genetic algorithm tuned fuzzy controller.
