Title:
CONTROL DEVICE DESIGN METHOD AND CONTROL DEVICE
Document Type and Number:
WIPO Patent Application WO/2014/084098
Kind Code:
A1
Abstract:
The present invention is a method for designing a control device whereby a control quantity of a plant is controlled to a target value, an objective whereof is to easily design a control device with both target value response and disturbance response supported, without applying a state equation. The control device is configured as a feedback control assembly, comprising a feedback controller wherein is inputted the difference between the target value and the control quantity, and a disturbance feedback wherein is outputted a disturbance estimate value wherein the difference between an output of a nominal plant wherein the output of the feedback controller is inputted and the control quantity is multiplied by a feedback gain, said feedback control assembly outputting an operation quantity of the plant on the basis of the feedback controller output and the disturbance estimate value. In response to a property of the plant, as a transfer function of the nominal plant, one transfer function is selected from a primary delay (+ waste time) transfer function, a secondary delay (+ waste time) transfer function, and a tertiary delay (+ waste time) transfer function, and on the basis of the nominal plant gain and a time constant, the transfer function of the feedback controller is determined.
