CONTROLLING WATER LEVEL BY USING MODIFIED MODEL FREE ADAPTIVE CONTROLLER

This paper investigates a simple mathematical model for water level system, which consists of DC motor (water pump), and Speed to Height transformation block, that relates the speed motor, height level. The input signal is applied voltage armature while output rotational shaft. A modified model-free adaptive controller suggested, control water, by adjusting rate incoming flow container, changing pump, fills container. suggested conventional free controller, combined with proportional integral derivative controller. parameters are tuned using two methods. overall controlled system simulated through MATLAB R2015a software. results show efficiency when compared PID MFAC, due its least fluctuation peak, fast response small settling time, zero steady-state error.
