Title: The Innovations of Koji Tomita
Introduction
Koji Tomita is a notable inventor based in Fukuoka, Japan. He has made significant contributions to the field of engineering, particularly in the development of advanced control systems. With a total of 4 patents to his name, Tomita's work has had a considerable impact on industrial machinery and automation.
Latest Patents
One of his latest patents is a position controller. This innovative device includes a position control part that calculates a speed command based on the difference between a position command and the rotation position of a motor. It also features a PI control part that computes a torque command based on the speed difference between the speed command and a feedback speed. Additionally, an observer generates the feedback speed based on the torque command and the motor's rotation speed. A phase lead compensator produces a phase lead compensation signal of the torque command based on the speed command, while an adder generates a new torque command by adding the phase lead compensation signal to the torque command.
Another significant patent is an operation confirming method and device for industrial machinery. This method enhances operation program correction efficiency by ensuring that the operation path during the confirming time (teaching mode) closely matches that during the actual job time (play mode). The method involves inputting respective shaft operation instruction values based on actual operation speed to a mechanical simulator, which then instructs a servo controller unit with a calculated quantity obtained from the mechanical simulator.
