摘要
用SIMULINK语言建立光电码盘的仿真模型,分析码盘测速值中包含噪声的原因及其对系统性能的影响。并提供了一种速度观测器以估计电机的瞬时速度。并用仿真结果证明以该观测器的输出构成的闭环系统对系统性能的影响。
After building an simulation model of optical encode with SIMULINK,the paper analyzes the cause of the noise involved in the velocity measurement of an encoder as well as the effect on the system performance. The paper provides a kind of velocity observer to estimate the instantaneous velocity a motor and tests the effect of the close-loop system composed of the output of the observer on the system performance with the simulation results.
