Patent number: 11507716Abstract: Methods, computer program products, and systems are presented. The methods include, for instance: obtaining service life data of a part including a maintenance operation count of the part. The life expectancy of the part is formulated as a function of a life span of the part and the maintenance operation count at a point in time based on the obtained service life data and data interpolated therefrom. A life expectancy model is built based on the function and a plurality of life expectancies are predicted by applying simulated inputs to the life expectancy model. The life expectancies are produced after verification to indicate when to replace the part.Type: GrantFiled: July 9, 2018Date of Patent: November 22, 2022Assignee: INTERNATIONAL BUSINESS MACHINES CORPORATIONInventors: Michihiro Yokoyama, Junya Shimizu

Method, article of manufacture, and system for configuring controller in sliding-mode control scheme
Patent number: 8942832Abstract: Method, article of manufacture and system using minimum data to determine whether a sliding-mode control should be applied in a plant. First measure the plant in an open-loop control fashion, and using the measured data, describe a state equation of the plant by system identification and order determination methods. Then design a switching hyperplane for sliding-mode control. Next, calculate higher order statistics on the difference between an output of a linear model on the hyperplane and an output of the sliding-mode control model in the measured data; When any of the higher order moments is larger than a predetermined threshold, configure a controller as a sum of the linear control input term and the nonlinear control input term. If both higher-order moments are smaller than the threshold, then configure the controller using only a linear control input term.Type: GrantFiled: November 8, 2011Date of Patent: January 27, 2015Assignee: International Business Machines CorporationInventor: Junya Shimizu -

Patent number: 8874411Abstract: A processing system, method, and program for a modeling system. A math equation including a differential equation is prepared. A CAS solves the differential equation normally and by using an interval coefficient in accordance with an interval analysis technique. A coefficient vector of the two solutions are compared to determine if a distance between the vectors is equal to or less than a preset value, and if so, the CAS solves the math equation including a differential equation with the target coefficient set to zero. The coefficient vectors of the solution thus obtained and the normally solved solution are compared to determine if the distance between the vectors is equal to or less than a preset value, and if so, the differential equation is simplified by omitting a term of the target coefficient from the differential equation.Type: GrantFiled: December 8, 2010Date of Patent: October 28, 2014Assignee: International Business Machines CorporationInventors: Hiroshi Ishikawa, Takashi Sakairi, Junya Shimizu
