Background: In this paper, fuzzy pole placement control approach is proposed to control speed of D.C motor. In this method, state feedback gain is tuned by fuzzy logic. Methods: In conventional pole placement control, constant gain is considered to insert the poles of system in desired place. Therefore, unnecessary effort is applied in the system, and system implementation becomes costly. In contrast, in fuzzy pole placement control, poles of system alter gradually based on performance of system and are settled in desired point causing the system to display apposite performance. In other words, in conventional pole placement, a determined pair of poles exists, whereas in fuzzy pole placement method an area, in which pair of poles is relocated, is obtained. Pair of poles changes its place based on recent behavior of system to have more appropriate manner. Results: As a result, state feedback gain changes intelligently according to on-line performance of system eventuating in acceptable outcomes. Results show that this approach is effectual and sound.
