Publication number: 20170030216Abstract: A dynamic system estimation device and method, whereby estimation for more performance parameters than there are sensors can be performed, the estimation taking temporal changes into account. The dynamic system estimation device includes: a prescribed number of sensors that detect prescribed observation values from a gas turbine engine; and a Kalman filter that uses a dynamic model of the gas turbine engine and estimates the state of the gas turbine engine, on the basis of the observation values detected by the sensors. The gas turbine engine includes an element having changes in temporal performance recorded by performance parameters. The Kalman filter enables more than the prescribed number of performance parameters to be estimated, as a result of introducing a first-order lag element in place of the element.Type: ApplicationFiled: July 28, 2016Publication date: February 2, 2017Applicant: IHI CorporationInventors: Hiroyuki FURUKAWA, Daiki KAKIUCHI, Mai KIMURA

Patent number: 9089914Abstract: A wire electric discharge machine has a function for controlling the machining liquid temperature. When it is predicted that the machining liquid temperature rises linearly, the machining liquid begins to be warmed at time t5b to reach machining liquid control temperature T2 at human operation beginning time t2. If the temperature rise at predetermined later time t8 is greater than predicted, temperature rising suspended from time t8 to a later time t9. Temperature rising resumed at time t9. This allows the machining liquid temperature to reach the machining liquid control temperature T2 without wasting electric power.Type: GrantFiled: November 27, 2012Date of Patent: July 28, 2015Assignee: FANUC CORPORATIONInventor: Hiroyuki Furukawa
