Abstract

In this paper, a minimum variance control system is proposed and practically implemented, which is adequate to the induction motor speed control system with frequent load variation. Minimum variance control method is used as a control law and recursive least square method with selective forgetting factor is proposed and analyzed with general forgetting algorithm as an estimation method. Designed control system is based on PC-DSP structure for the purposed of easiness of applying adaptive algorithm. Through computer simulation and experimental results, it is verified that proposed control system is robust to the load variation and practical implementation is possible.

본 연구는 부하변동이 갖은 유도 전송기 속도제어 시스템에 적합한 최소분산제어 알고리즘을 제안하고 구현을 실제적인 파라미터 추정방법을 제안한다. 그리고 고속 연산 신호처리요 프로세인 TMS 320C25를 이용한 제어 시스템을 구성한다. 적응칙은 선택적 망각인자를 갖는 순환형 최소자승법이 실제적 구현의 관점에서 언급되며, 일반적인 망각인자 알고리즘과 비교분석한다. 제어칙은 최소분산 제어 알고리즘으로 한다. 제어시스템은 알고리즘의 적용이 용이하도록 PC에 기초한 DSP제어 시스템으로 설계 제작한다. 시뮬레이션과 실험을 통하여, 본 연구의 초소분산제어 시스템이 부하변동에 강인한 구조를 갖고 있으며 유도전동기 제어에 실제적 구현이 가능함을 입증한다.
