Abstract
본 논문은 실시간 음성인식명령으로 구동되는 지능형 이동기제어시스템을 제안한다. 제안된 이동기제어시스템은 메인모듈, 음성인식모듈, 모터구동모듈, 센서모듈로 구성된다. 80C196KC로 구현된 메인모듈에서 퍼지논리가 적용된 지능형 제어시스템을 제안한다. 사용자의 몸무게 및 여러 가지 주변 환경요인들에 의한 비선형성을 개선하기 위해서 피드백제어가 가능한 모터구동모듈과 센서모듈이 구현된다. 또한 제안된 시스템에서 이동로봇의 제어를 위한 9개의 단어를 사용하여 동작을 테스트하였고, 제어입력으로 음성명령과 조이스틱 사용 시 이동로봇의 성능을 평가하였다. This paper presents the design of intelligent moving machine control system using a real time speech recognition. The proposed moving machine control system is composed of four separated module, which are main control module, speech recognition module, servo motor driving module and sensor module. In main control module with microprocessor(80C196KC), one part of the artificial intelligences, fuzzy logic, was applied to the proposed intelligent control system. In order to improve the non-linear characteristic which depend on an user's weight and variable environment, encoder attached to the servo motors was used for feedback control. The proposed system is tested using 9 words lot control of the mobile robot, and the performance of a mobile robot using voice and joystick command is also evaluated.
