How to adjust the balance of double-capacity water tank
1. Firstly, based on the principle of liquid level balance, the mathematical model of liquid level control system of double-tank is established, and the linearization model is established by using the linearization method of equilibrium point.

2. Secondly, fuzzy PID control method is used to adjust the parameters of PID controller on line to realize the adjustment of liquid level of double-tank water tank, and a detailed control scheme is given.

3. Finally, the simulation block diagram is built by using Simulink to realize system simulation, adjust PID parameters online and analyze system performance. You can adjust the balance.
