Water Tank Level Control Based on Fuzzy Self-tuning PID
The liquid level control system of water tank has the characteristics of time delay,large inertia and uncertainty,so it is difficult to adjust the liquid level quickly and accurately by using the traditional Proportional Integral Derivative(PID).Therefore,the fuzzy control theory is introduced and the PID control parameters are adjusted according to the actual situation by using its adaptive learning ability to better adapt to the parameter changes of the water tank level control system.The simulation experiment of the water tank level control system shows that the fuzzy self-tuning PID control can effectively reduce the response time and overshoot of the system,and strengthen the fast response and robustness of the system.In addition,the effectiveness of fuzzy self-tuning PID control in resisting interference is verified by random disturbance simulation.
