摘　　要：用 SIMU LINK语言建立起了光电码盘的仿真模型 ,分析了码盘测速值中包含噪声的原因及其对系统性能的影响。在此基础上提出了一种速度观测器以估计电机的瞬时速度。A method of modeling optical encoders has been developed using SIMULINK. Noise included in the value of velocity measured by an encoder and its impact on performances of a closed loop system has been analyzed.On the basis of this,an observer is constructed to estimate the instantaneous velocity of a motor.Simulation results show the performance of closed loop system is improved using the output of the observer as feedback.
