The 2DOF controller implementation in control system with single-chip computer

This paper deals with an application of two degrees of freedom controller (2DOF) on a controlled system. The control system is based on a single-chip microcontroller (MCU). The communication is provided by the serial interface which is between an industrial personal computer (IPC) and MCU. The controlled system is monitored and controlled by SCADA/HMI system. The PI 2DOF controller is designed for DC motor. The achieved results confirm theoretical assumption about process quality.
