| Abstract |
In this paper the developed low cost embedded system for liquid level control of tank is presented. The plant is a physical laboratory model of a water tank. The liquid level is controlled in wide range by designed LQG controller. The LQG controller is designed on the basis of obtained by identification linear black box model. A software in MATLAB®/Simulink® environment for generation of code which is embedded in low cost control kit ARDUINO Mega 2560 is developed. Simulation and experimental results are given that confirm the workability of the embedded control system |
