퍼지뉴로 제어기를 이용한 PI 제어기의 성능 개선 및 IPMSM의 속도제어

This paper proposes speed control of IPMSM and performance improvement of PI controller using fuzzy-neuro controller. To apply industrial processes, control methods is requested technique that can be demonstrate high performance and robust about load disturbance, parameter variation and uncertainty of model, etc. PI controller does not show satisfactory performance due to fixed gain. Therefore, this paper proposes FN-PI which is adjusted input values of PI controller with operating conditions of motor by FNN controller mixed neural network and fuzzy. And this paper proves validity of proposed control algorithm through result analysis.
