Position control of permanent magnet dc motor with state space approach

The system with multi input and multi output are frequently encountered in processes steps of actual industrial applications. To provide controlling of these steps sensitively it is needed to determine requirements of process steps and perform models for those steps. In the present study firstly an equation was acquired for permanent magnet DC motor to provide position controlling. State space model of the motor was obtained using that equation. Pole replacement technique was applied to the model firstly. Secondly state observer method was applied. As third step, linear quadratic regulation (LQR) technique was used so the controller was designed. Output of the system was observed by MATLAB software simulation of acquired result data which were attained using by three techniqueKeywords: DC Motor, State Observer, Pole Placement, LQR (Linear Quadratic Regulation), MATLAB.
