Patent number: 8712559Abstract: Systems and methods of adaptive control for uncertain nonlinear multi-input multi-output systems in the presence of significant unmatched uncertainty with assured performance are provided. The need for gain-scheduling is eliminated through the use of bandwidth-limited (low-pass) filtering in the control channel, which appropriately attenuates the high frequencies typically appearing in fast adaptation situations and preserves the robustness margins in the presence of fast adaptation.Type: GrantFiled: February 9, 2011Date of Patent: April 29, 2014Assignees: The Board of Trustees of the University of Illionois, University of ConnecticutInventors: Chengyu Cao, Naira Hovakimyan, Enric Xargay

Patent number: 8682454Abstract: A method and system for controlling a multivariable system. The method includes: (a) generating bias data as a function of model error in an on-board model; (b) updating a dynamic inversion algorithm with one or more model terms generated by the on-board model; (c) generating effector equation data by processing reference value data with the updated dynamic inversion algorithm, which effector equation data is indicative of one or more goal equations and one or more limit equations, and which reference value data is indicative of one or more goal values and one or more limit values and is determined as a function of predicted parameter data; (d) at least partially adjusting at least one of the reference value data and predicted parameter data for the model error using the bias data; and (e) generating one or more effector signals by processing the effector equation data with an optimization algorithm.Type: GrantFiled: February 28, 2011Date of Patent: March 25, 2014Assignee: United Technologies CorporationInventors: James W. Fuller, Richard P. Meisner

Publication number: 20140081427Abstract: The invented controller tuning method relies on the following procedure. To the controlled system with known proportional gain the integral type controller is connected in series. The controller gain kl is increased to get the closed loop system to the stability limit. At this stage the controller ultimate gain ku and the sustained oscillation period period Tosc of the controlled value are assessed. It is assumed that the controlled system dynamics can be approximated by the first order filter with dead time model. The following formulas allow to estimate the first order filter time constant F(1) and the coefficient ?=L/T=(arcctg(?oscT))/(?oscT) where L is the dead time constant of the controlled system model. From the formulas: F(2) the controller model parameters are calculated.Type: ApplicationFiled: May 28, 2012Publication date: March 20, 2014Applicant: POLITECHNIKA SWIETOKRZYSKAInventors: Miroslaw Wcislik, Michal Laskawski

Patent number: 8676356Abstract: A system and method for determining unknown values of certain motor parameters includes a motor input device connectable to an electric motor having associated therewith values for known motor parameters and an unknown value of at least one motor parameter. The motor input device includes a processing unit that receives a first input from the electric motor comprising values for the known motor parameters for the electric motor and receive a second input comprising motor data on a plurality of reference motors, including values for motor parameters corresponding to the known motor parameters of the electric motor and values for motor parameters corresponding to the at least one unknown motor parameter value of the electric motor. The processor determines the unknown value of the at least one motor parameter from the first input and the second input and determines a motor management strategy for the electric motor based thereon.Type: GrantFiled: January 9, 2009Date of Patent: March 18, 2014Assignee: Eaton CorporationInventors: Bin Lu, Ting Yan

Patent number: 8666515Abstract: A computer-implemented initial run module processes manifest variable data using computer-defined model specification parameters stored in a database to provide initial estimates of weights that are associated with latent variables. The initial run module employs a unique value-based weighting partial least squares computer-implemented process. A final run module then operates upon the manifest variable data to determine the importance of the predictor values that are then used to control the industrial, manufacturing or commercial process. The final run module implements a unique patient partial least squares regression model utilizing a boosting learning technique.Type: GrantFiled: January 7, 2009Date of Patent: March 4, 2014Assignee: CFI Group USA, LLCInventors: Claes Fornell, Jaesung Cha, Philip Debard Doriot

Patent number: 8577747Abstract: Methods and systems for use in acquiring parts from suppliers using auction information including a requested part and decision criteria from an ordering manager agent and from supplier agents associated with part suppliers. A criteria comparison matrix representing a relative importance of each decision criterion is created. A criteria importance vector is created based on the criteria comparison matrix, and a supplier comparison matrix corresponding to each decision criterion is also created. The supplier comparison matrix represents a relative ranking of each supplier with respect to the corresponding decision criterion. A supplier criteria ranking vector corresponding to each decision criterion is created based on the supplier comparison matrix that corresponds to the decision criterion. The supplier criteria ranking vectors and the criteria importance vector are combined to create a supplier score matrix associated with the ordering manager agent and indicating a score associated with each supplier.Type: GrantFiled: July 17, 2011Date of Patent: November 5, 2013Assignee: The Boeing CompanyInventors: William E.
