        abstract = {When multiple tanks interact through shared flows, changes in one tank can alter the behaviour of the others, making level regulation more demanding than in single-tank systems. This work investigates such interactions using the Quadruple Tank System, a four-tank configuration commonly used to study multivariable control challenges. A mathematical model of the system is developed based on basic flow dynamics and mass-balance principles. Using this model, a PID controller is designed to regulate the levels of the two lower tanks, with controller gains determined through manual tuning and evaluated through simulation. The results show that the controller guides the tank levels toward their setpoints, although coupling effects cause overshoot and slower settling. These findings serve as a starting point for future improvement using optimization-based tuning methods.},
