Implementation of a dSPACE DSP-based state feedback with state observer using Matlab/Simulink for a speed control of DC motor system

This paper presents design and implements the state feedback controller to design using Matlab/simulink for a speed control system of DC motor. The proposed controller will be a state feedback with state observer controller incorporating integrator. The controller design by pole placement technique is also introduced to the system for regulates and tracking speed response. The overall control system is implemented on dSPACE DSP DS1104 controller board. This scheme leads to be able to adjust the speed of the motor by control the input voltage of power amplified. The experimental results in testing the 48 watt DC motor system from no load condition to rated condition show the effectiveness of the proposed control scheme. It is found that the motor speed can be controlled to be constant in the operating range of 0-3200 rpm at no load and full load.
