Title:
PARAMETER ESTIMATION METHOD FOR HYDRAULIC SYSTEM
Document Type and Number:
WIPO Patent Application WO/2019/058905
Kind Code:
A1
Abstract:
Provided is a parameter estimation method by which a physical quantity affecting the dynamic characteristics of a hydraulic system is estimated as a parameter, and which can be widely applied. This method is provided with: a step for selecting, from a state vector including a state quantity of a hydraulic system and a parameter of an estimation target, a corresponding state quantity and a corresponding estimation target parameter, thereby setting a corresponding state vector; a step for using the set state vector to set a state equation of the hydraulic system; and a step for applying a state estimation method based on Bayes estimation to the state equation, thereby estimating the value of the estimation target parameter included in the state vector.
