A New Variable-Structure Position Control for DC Motor Using Fuzzy Logic

퍼지논리를 이용한 직류전동기용 가변구조 위치제어시스템

This paper presents a new dc-motor position control approached by Variable Structure System. In order to eliminate a steady-state position error, we propose a switching function composed of position error, velocity, and current ripple. The switching function has an advantage compared to other ones. To determine the control signal voltage, we use a fuzzy logic method. The simulation results show expected performances.
