Abstract: This paper presents the generalized dynamic modeling of dc motor using state space approach. The performance of dc motor under various conditions is simulated using MATLAB/SIMULINK environment and simulation result demonstrates the feasibility of the proposed system. A state feedback gain matrix is designed for the dc motor with the help of pole-placement technique. Direct substitution method is used to design state observer matrix for the motor. Both derived matrix are used to determine the transfer function of the full order observer controller in MATLAB environment.
