Latest Patents

Usui's latest patents include a control device, model creation method, and control program. The first patent describes a control device that utilizes a dynamics model to perform model predictive control for each control period. This model represents the relationship between a manipulated variable and the position of a controlled object. It generates a manipulated variable to be output to the servo driver. The dynamics model consists of two components: a first dynamics model that relates the manipulated variable to the servomotor's position, and a second dynamics model that connects the servomotor's position to the controlled object's position. The second model is created using a waveform parameter extracted from the controlled object's vibration waveform, which includes a vibration frequency.

The second patent outlines a control device connected to a servo mechanism that drives a controlled object. This device outputs a manipulated variable to ensure that a controlled variable tracks a target trajectory. It includes a controller and a sensor. The controller acquires measured values from the sensor and performs model predictive control based on the dynamics model. The sensor measures the position of the controlled object, allowing the controller to operate in two modes depending on the object's position.
