The PID controllers are widely used in industry control applications due to their effectiveness and simplicity. This project presents PID controller design for MIMO coupled water tank level control system that is second order system. PID Controller output is fuzzified to control water level in coupled tank system. Simulation has been done in Matlab (Simulink library) with verification of mathematical model of controller. PID controller design and program has been prepared in LabVIEW. At the place of proportional valve, combinations of solenoid valves are used. The NI DAQ card is used for interfacing between hardware and LabVIEW software. Experiment is fully triggered by LabVIEW. Simulated results are compared with experimental results.

Frequently Asked Questions
What is a PID controller?
A Proportional-Integral-Derivative (PID) controller is a control loop mechanism widely used in industrial systems to maintain a desired output by adjusting inputs based on error values.
What does MIMO stand for?
MIMO stands for Multiple-Input Multiple-Output, referring to systems that have more than one control input and more than one measured output, like coupled water tanks.
Why fuzzify the PID controller output?
Fuzzification allows for more flexible and precise control in non-linear systems or when using discrete components like solenoid valves instead of proportional valves.
What is the role of LabVIEW in this project?
LabVIEW is used as the primary software platform for designing the controller, programming the logic, and interfacing with the hardware via a DAQ card.
How are solenoid valves used in this system?
Combinations of solenoid valves are used to control the water flow, acting as a discrete alternative to more expensive proportional valves.
