Abstract: In this paper, a dynamic model of DC motor using state space approach has been established. A state space observer model has been developed for the armature of a DC motor based on its torque, speed and electrical system equations and similarly flux control for field controlled DC motor. The systems controllability and observability is studied in each case and the performance of the DC motor is studied under various conditions and its determined whether such a system with given parameters can be realized or not. A state feedback system is also determined using pole-placement method. The implementation of the systems and their verification is done using MATLAB and Simulink.
