Observer für Geschwindigkeitssteuerung in einem Geschwindigkeitssteuerungssystem für einen Motor

摘要

A speed estimation observer for a motor control system outputs a motor speed estimate @ (i) in a motor speed control system upon receiving a torque command ( tau M*(i)) and an averaged motor speed value nM(j). The speed estimation observer includes a time lag correction value calculating block for implementing a correction of a model output speed estimate. Therefore, the accuracy and stability of the speed estimation are improved, and the control system keeps the stability in a speed range of low to high speed and ensures the disturbance suppressing effect in a high speed range.
