Application: Control device (Patent ID: US20230418241A1)

The patent filed by Kobe Steel Ltd. describes a control device that includes a static compensator and a dynamic compensator to calculate compensatory inputs based on static and dynamic parameters, respectively. These compensatory inputs are synthesized to calculate an actual input that is then used to control a controlled object. An ideal output calculator is used to determine an ideal output based on a control input, and a parameter adjuster is employed to minimize the difference between the control output and the ideal output by adjusting the static and dynamic parameters.

The claims of the patent further detail the components and functions of the control device, including the calculation of static and dynamic compensatory inputs, adjustment of parameters such as proportional gain and derivative gain, and the use of recursive least squares for parameter adjustment. The control device is particularly suited for controlling a hydraulic system with components such as a hydraulic pump, electric motor, and actuator, where the control output is the state value of the actuator and the actual input is an instructive value to the electric motor. Overall, the patent outlines a comprehensive control system that effectively minimizes errors between target and actual outputs through the adjustment of static and dynamic parameters.
