Title: Innovations by Yasuhiro Kanazashi: A Look into His Contributions
Introduction
Yasuhiro Kanazashi, an accomplished inventor based in Numazu, Japan, has made significant contributions to the field of electric motor control. His innovative work has resulted in the development of a unique position control device for electric motors, addressing key challenges in the industry.
Latest Patents
Yasuhiro holds one notable patent: the Position Control Device for Electric Motor. This invention inputs deviation signals between the angle command and angle detection value to a position control section, where it calculates the angular velocity command. It further processes deviation signals between this angular velocity command and the angular velocity detection value to a speed control section, leading to the calculation of the torque current command. The control of the electric motor is implemented according to this torque current command, enhancing the precision and reliability of motor operations.
The Position Control Device contains several critical sections. The disturbance observer section inputs the torque current command and the angular velocity detection value, estimating signals that correspond to disturbance torque. Additionally, a rate-of-change limitation section implements limiters that process disturbances, performing rate-of-change constraints on the upper and lower limits of the angle command. Lastly, the target value filter section, set with control gain equivalent to the speed control section, allows the angular velocity command from the position control section to pass through seamlessly.
