Patent number: 11754992Abstract: A control device is connected to a servo mechanism that drives a controlled object and outputs a manipulated variable to the servo mechanism so that a controlled variable tracks a target trajectory. The control device includes a controller and a sensor. The controller acquires a measured value from the sensor and performs model predictive control for each control period using a dynamics model representing a relationship between the manipulated variable and the position of the controlled object to generate the manipulated variable to be output to the servo mechanism. The sensor measures the position of the controlled object. The controller performs model predictive control in a first mode using the measured value when the controlled object has a position within the range, and performs model predictive control in a second mode using an output value of the dynamics model when the controlled object has a position outside the range.Type: GrantFiled: January 23, 2020Date of Patent: September 12, 2023Assignee: OMRON CORPORATIONInventors: Masaki Namie, Yukio Iname, Yoshimasa Usui

Patent number: 10732587Abstract: Compensation for an external disturbance can be applied without requiring a model of the external disturbance, and, particularly, the amount of control can be accurately predicted even when the amplitude of a waveform representing changes in a predicted error with respect to time is not constant with respect to time in a case in which the predicted error that is an error between an actually-measured value of the amount of control of a control target and a predicted value periodically changes. A controller compensates a predicted value of the current amount of control using a predicted error of a previous period by taking changes in the amplitude of a waveform representing a predicted error that is an error between an actually-measured value of the amount of control and a predicted value into account.Type: GrantFiled: November 14, 2018Date of Patent: August 4, 2020Assignee: OMRON CorporationInventors: Masaki Namie, Yukio Iname
