This article presents an advanced solution to the speed tracking problem of permanent magnet synchronous motors subject to two practical concerns: uncertain motor parameter values, load variations, and current feedback dependence level. The results present a few contributions for industrial

application: (a) a parameterindependent angle filter (providing speed and acceleration estimates) by modifying the structure of the conventional

extended state observer, (b) the angle filter-based pole-zero cancellation acceleration stabilizer removing the q-axis current dependence of the speed

loop, and (c) the adaptive speed loop in the analytic form to improve the tracking performance by boosting feedback gain during only the transient

periods. Using a dynamo testbed adopting a 700-W PMSM as the test motor, this experimental study verifies the effectiveness of the proposed

technique under various operating modes.
