摘要

对基于观测器的闭环速度控制方案对负载转矩扰动、驱动参数变化和观测器极点位置的敏感性进行了理论分析和实验验证。这些结果也证明了观察者-控制器分离原理。给出了观测器设计对零初始条件下估计收敛性的影响。通过将计算信号与轴位置传感器的输出进行比较，还验证了从观测到的速度计算轴位置的有效性。

Experimental study of an observer-based shaft sensorless variable speed drive

An experimental study of an observer-based closed-loop speed control scheme sensitivity to load torque disturbances, drive parameter variations, and observer pole location is analyzed theoretically and verified experimentally. These results demonstrate the observer-controller separation principle as well. The effect of observer design on estimation convergence from zero initial conditions is shown. The effectiveness of computing the position of the shaft from the observed speed is also tested by comparing the computed signal with the output of a shaft position sensor.<>
