Abstract

The paper presents mathematical model of absolute optical encoder with parallel gray output where various parameters of the transducer can be modified (ex. number of bits, asymmetry in output waveforms, lack of signals from selected bits). The model of the non - ideal encoder substitutes the model of ideal position sensor implemented in Matlab/Simulink model of three phase PMSM (Permanent Magnet Synchronous Motor) drive with SVPWM (Space Vector Pulse Width Modulation) control algorithm. The author examines the impact of: asymmetry in output signals from the encoder and absence of signals from selected bits (simulation of damage of the transducer) to the static and dynamic properties of the drive in current and speed control loop mode. Selected methods of signal improvement were implemented in order reproduce the degradated position signal. The simulation results are verified by experiment. Quality indicators are proposed in order to determine the rate of damage of the encoder/drive. Conclusions and proposes of further research are presented.

绝对位置换能器劣化对永磁同步电机电传动的影响

本文提出了一种具有平行灰度输出的绝对式光学编码器的数学模型，该编码器的各种参数(如比特数、输出波形的不对称、所选比特的信号缺失)都可以修改。该非理想编码器模型用空间矢量脉宽调制(SVPWM)控制算法代替了在Matlab/Simulink中实现的理想位置传感器模型。作者检查了编码器输出信号的不对称和选定位信号的缺失(模拟换能器的损坏)对驱动器在电流和速度控制回路模式下的静态和动态特性的影响。为了再现降级后的位置信号，采用了一定的信号改进方法。通过实验验证了仿真结果。提出了质量指标，以确定编码器/驱动器的损坏率。最后提出了进一步研究的结论和建议。
