Title:
PERFORMANCE ESTIMATION DEVICE AND PERFORMANCE ESTIMATION METHOD
Document Type and Number:
WIPO Patent Application WO/2018/055825
Kind Code:
A1
Abstract:
A performance estimation device according to one aspect of the present disclosure outputs, on the basis of a control input value for controlling a target device and a sensor measurement value measured by a sensor disposed in the target device, a state estimation value that is an estimated value of a state quantity of the target device and is impossible to be measured by the sensor. The performance estimation device is provided with: an estimation unit for calculating a state estimation value and a sensor estimation value by using a non-linear simulation model of the target device; an error calculation unit for calculating an error between the sensor estimation value and the sensor measurement value; a gain storage unit for storing a first gain corresponding to a first operation point and a second gain corresponding to a second operation point; a gain determination unit for determining, on the basis of the first gain and the second gain, a set gain at a set operation point that is an operation point at which the target device is operating; and a correction unit for generating a correction value on the basis of the error and the set gain, wherein the estimation unit calculates the state estimation value and the sensor estimation value on the basis of the control input value and the correction value and outputs the state estimation value.
