  • Publication number: 20240110364
    Abstract: A pump control device and a valve control device each includes: an instruction calculator that calculates a control instruction of causing a controlled object to operate by using a manipulation amount of a manipulation and at least one control parameter, and inputs the calculated control instruction to the controlled object; and an ideal output calculator that calculates an ideal output of an actuator, the ideal output being associated with the manipulation amount of the manipulation. The pump control device adjusts at least one pump control parameter to reduce a difference between a control output and the ideal output when an operation of a movable part is a power running operation. The valve control device adjusts at least one valve control parameter to reduce a difference between a control output and the ideal output when the operation of the movable part is a non-power running operation.

  • Publication number: 20230418241
    Abstract: A control device includes: a static compensator that calculates, on the basis of a static parameter, a static compensatory input; a dynamic compensator that calculates, on the basis of a dynamic parameter, a dynamic compensatory input; a subtractor that calculates an actual input by synthesizing the static compensatory input and the dynamic compensatory input; an ideal output calculator that calculates an ideal output responsive to a control input by using an input and output model defining an ideal input and output relation between a control input and a control output; and a parameter adjuster that adjusts the static parameter and the dynamic parameter to minimize a difference between the control output and the ideal output.

  • Publication number: 20220229427
    Abstract: To keep plant performance constant in a control apparatus for controlling a plant including a plurality of units. The control apparatus (a PCM) controls an automobile including a plurality of units. The control apparatus includes a model controller that generates a target value of a characteristic to be achieved by each unit based on a model set for each unit, a unit specifier (a performance change determinator) that specifies a unit in which performance unique to the unit has changed among the units, and a target value corrector (an FF updater) that corrects the target value for the unit that has been specified by the unit specifier.
