【Abstract】 This paper presents a simulation of the speed control of a series DC motor using fuzzy logic control(FLC)at MATLAB environment.The fuzzy logic controller designed in this study determines the required PWM duty cycle used in the DC chopper control based on motor speed error and its change.The simulation results show that the system has a fast response,smooth low-speed,small steady-state error,high-precision speed control.更多还原
