PID Control Simulation is an educational application designed for Android devices that offers a practical simulation of a hot and cold water vessel mixer. Users can interact with three PID control valves to manage vessel water temperature, vessel level, and outlet flow of mixed water. The app allows users to adjust the set-points for these parameters as well as modify PID control parameters, providing an engaging way to learn about control systems.

The application emphasizes mass and heat balance calculations, making it a valuable tool for students and professionals in engineering and related fields. Its user-friendly interface is designed to facilitate understanding of PID control mechanisms through hands-on experience. This free app serves as an effective resource for those looking to enhance their knowledge of fluid dynamics and control theory.
