Patent number: 7218999Abstract: A target value processing unit, includes: an input section to which a target value signal showing a target value of a control process is inputted; a target value shaping unit shaping the target value signal inputted to the input section, into a signal form which is proper for a control treatment of a regulator implementing the control process; and an output section outputting to the regulator a shaped target value signal which is shaped by the target value shaping unit. The target value processing unit realizes the high-level control process without improving the regulator.Type: GrantFiled: February 23, 2005Date of Patent: May 15, 2007Assignee: Omron CorporationInventors: Nobutomo Matsunaga, Shigeyasu Kawaji, Ikuo Nanno, Masahito Tanaka, Takaaki Yamada, Yosuke Iwai, Takeshi Wakabayashi, Kazuo Tsuboi

Patent number: 7184020Abstract: An operation instructing device is included substantially at the center of a portable apparatus, and has a sensor for detecting motion values of the portable apparatus. A user performs various movements instructed by an instructing unit, while holding the portable apparatus. The motion values detected by the sensor are normalized by an analyzing unit, and then an area setting unit sets a movement detecting area personally for the user. An assigning unit obtains operation instructions for each function of the portable apparatus, and generates an operation instruction table in which each instruction operation is assigned to a sub area of the movement detection area. A judging unit judges within which sub area the motion value notified by the analyzing unit falls, and outputs the operation instruction that is assigned to the sub area within which the judging unit judged that the notified motion value falls.Type: GrantFiled: October 14, 2003Date of Patent: February 27, 2007Assignee: Matsushita Electric Industrial Co., Ltd.Inventor: Gantetsu Matsui

Patent number: 7110834Abstract: A kiln thermal and combustion control. A predictive model is provided of the dynamics of selected aspects of the operation of the system for modeling the dynamics thereof. The model has at least two discrete models associated therewith that model at least two of the selected aspects, the at least two discrete models having different dynamic responses. An optimizer receives desired values for the selected aspects of the operation of the system modeled by the model and optimizes the inputs to the model to minimize error between the predicted and desired values. A control input device then applies the optimized input values to the system after optimization thereof.Type: GrantFiled: September 23, 2003Date of Patent: September 19, 2006Assignee: Pavilion Technologies, Inc.Inventors: Gregory D. Martin, Eugene Boe, Stephen Piche, James David Keeler, Douglas Timmer, Mark Gerules, John P. Havener, Steven J. McGarel

Patent number: 7057366Abstract: A method for estimating load inertia and system for controlling motor speed using inverse model are provided, suitable for an alternating current (AC) servo module. An inverse system is connected to an actual system to inversely deduce a substantial torque output, wherein when the value of the speed signal generated by the actual system gradually increases, a net inertia ratio is accumulated; whereas when the value of the speed signal generated by the actual system increases to a fixed value, the net inertia ratio is updated.Type: GrantFiled: September 27, 2005Date of Patent: June 6, 2006Assignee: Delta Electronics, Inc.Inventors: Ching-Hsiung Tsai, Jia-Ming Wu

Patent number: 7050883Abstract: An off-line feed rate scheduling method of a CNC machining process includes selecting a constraint variable and inputting a reference value related to the constraint variable; estimating a cutting configuration where a maximum constraint variable value (CVV) occurs through ME Z-map modeling; receiving the estimated cutting configuration and estimating a specific rotation angle (?s) where the maximum constraint variable value occurs through constraint variable modeling; calculating a feed rate that satisfies the reference value of the constraint variable at the estimated specific rotation angle; and applying the calculated feed rate to the NC code. Cutting force or machined surface error may be selected as a constraint variable depending on machining conditions.Type: GrantFiled: March 3, 2004Date of Patent: May 23, 2006Assignee: POSTECH FoundationInventors: Dong-Woo Cho, Jeong-Hoon Ko, Han-Ul Lee

Patent number: 7039475Abstract: The present invention provides a method for controlling nonlinear process control problems. This method involves first utilizing modeling tools to identify variable inputs and controlled variables associated with the process, wherein at least one variable input is a manipulated variable. The modeling tools are further operable to determine relationships between the variable inputs and controlled variables. A control system that provides inputs to and acts on inputs from the modeling tools tunes one or more manipulated variable inputs to achieve a desired result like greater efficiency, higher quality, or greater consistency.Type: GrantFiled: December 9, 2003Date of Patent: May 2, 2006Assignee: Pavilion Technologies, Inc.Inventors: Bijan Sayyarrodsari, Eric Hartman, Celso Axelrud, Kidir Liano
