Abstract

This paper presents the high performance control of interior permanent magnet synchronous motor(IPMSM) using space vector(SV) PWM method based on hybrid artificial intelligent(HAI) controller. The HAI controller combines the advantages between adaptive fuzzy control and neural network The SV PWM method is applied to a speed control system of motor in the industry field until now and is feasible to improve harmonic rate of output current, switching frequency and response characteristics. This HAI controller is used instead of conventional PI controller in order to solve problems happening when calculating a reference voltage. The HAI controller improves speed performance by hybrid combination of reference model-based adaptive mechanism method, fuzzy control and neural network. This paper analyzes response characteristics of parameter variation, steady-state and transient-state using proposed HAI controller and this controller compares with conventional fuzzy neural network(FNN) and PI controller. Also, this paper proves validity of HAI controller.

본 논문에서는 HAI(Hybrid Artificial Intelligent) 제어기반의 SV PWM 방식을 이용한 IPMSM의 고성능 제어를 제시한다. HAI 제어기는 적응 퍼지제어 및 신경회로망의 장점을 혼합 적용한다. SV PWM 방식은 지금까지 산업용 전동기 제어분야에 적용되고 있고 출력전류의 고조파 비율, 스위칭 주파수 및 응답특성을 향상시키는 수 있는 기법이다. HAI 제어기는 지령전압을 계산할 때 발생되는 문제점을 해결하기 위하여 종래의 PI 제어기를 대체하여 사용한다. HAI 제어기는 지령모델 기반의 적응제어, 퍼지제어 및 신경회로망으로 구성되어 속도 성능을 개선한다. 본 논문에서는 제시한 HAI 제어기를 적용하여 파라미터 변동, 정상상태 및 과도상태 등의 응답특성을 분석하고 종래의 FNN 제어기 및 PI 제어기의 응답특성과 비교한다. 따라서 본 논문에서는 HAI 제어기의 타당성을 입증한다.
