Title Study on Fuzzy Control of Water Level in the Water Tank .
Abstract
The water tank water level control system is widely used in every field, its core idea is fuzzy control.The application of fuzzy control in control system design does not need to know the precise mathematical model of the controlled object. For many complex systems which are unable to establish accurate mathematical models,it can obtain better control effect and also can simplify the system design. Therefore, in the water tank water level automatic control system, the fuzzy control becomes the best choice.
This paper has explored the fuzzy logic background and reported the development status of fuzzy control.It has made a deep research in the control system of water lever in the water tank.Through the MATLAB fuzzy logic toolbox and Simulink simulation combining,the thesis has completed the design of fuzzy controller, drawn the block diagram of the system.The simulation is successful under the Simulink environment and the water level of the animation process has come out.
