Latest Patents

Yao-Sheng Wu holds a patent for a "Method of estimating D-Q axis inductance of permanent magnet synchronous motor." This method involves several steps, including building an equivalent motor control block by enabling two of the three phases while disabling the remaining one and locking the rotor. The process incorporates a back EMF observer into a DC motor control block, which is then aligned with the back EMF observer by setting the angular speed of the DC motor control block to zero. The equivalent motor control block is introduced into the DC motor control block, allowing the back EMF observer to estimate the back EMF. This process is repeated by disabling one phase at a time to obtain three sets of motor inductances. Finally, the d-q axis inductance is estimated using an inductance relational equation that incorporates these three sets of equivalent motor inductances.
