Title: Innovations by Mitsuharu Matsuno
Introduction
Mitsuharu Matsuno is a notable inventor based in Kariya, Japan. He has made significant contributions to the field of motor control technology, holding a total of 3 patents. His work primarily focuses on enhancing the efficiency and performance of alternating current motors.
Latest Patents
Matsuno's latest patents include a control device for alternating current motors. In one of his inventions, a standard voltage calculation part computes a d-axis standard voltage and a q-axis standard voltage in a state where no demagnetization occurs in the permanent magnets of a motor generator (MG). Additionally, a magnetic flux change amount estimation value calculation part determines a basic magnetic flux change amount estimation value based on the deviation of a specific value from the q-axis standard voltage. This specific value is derived by multiplying the q-axis real voltage with the ratio of the d-axis standard voltage to the d-axis real voltage. Furthermore, a magnetic flux change amount estimation value correction part adjusts this estimation value relative to a detection threshold based on the characteristic changes of the MG during demagnetization.
Another patent also focuses on a control device for alternating current motors, where a standard voltage calculation part calculates the d-axis and q-axis standard voltages to be supplied to the MG. A first magnetic flux change amount estimation value calculation part computes an estimation value based on the deviation of a specific value from the q-axis standard voltage. This specific value is obtained by multiplying a ratio of the d-axis standard voltage to the d-axis real voltage with the q-axis real voltage. A second magnetic flux change amount estimation value calculation part calculates another estimation value based on the deviation of the q-axis real voltage from the q-axis standard voltage. The calculation switching part selects between these estimation values based on the operational state of the MG.
