Patent number: 6208914Abstract: A system for adaptive and reconfigurable control of aircraft and other complex objects and processes, herein referred to collectively as controlled “plants.” A modified form of sequential least-squares estimation is used to obtain near-real-time estimates of the values of plant parameters. The parameter estimates are used in a novel piecewise-linear optimal receding-horizon sampled-data controller in which internal controller parameters, known in the art as Riccati gains, are propagated from their current values using the most recent plant parameter estimates. This method of updating Riccati gains is a major departure from the prior art in receding-horizon control, where the Riccati gains (or equivalent) are re-initialized at each control update using terminal boundary conditions. The present invention provides improved robustness of control, lessened need for re-tuning control-effort penalties when operating conditions change, and significantly reduced computational burden.Type: GrantFiled: November 19, 1997Date of Patent: March 27, 2001Assignee: Barron Associates, Inc.Inventors: David G. Ward, Jeffrey F. Monaco, Roger L. Barron, Rebecca A. Bird

Patent number: 5913051Abstract: Simulation of a complex system begins by generating a plurality of system objects (12) describing items within the system through structural information within the system object (12). Each system object (12) corresponds to a plurality of parameter group objects (18, 20, 22), and a plurality of state objects (24, 26, 28) associated therewith. Each system object (12) also corresponds to a plurality of simulation objects (30, 32, 34) representing specific simulations of the complex system.

Patent number: 5613183Abstract: The disclosure relates to a method of binder removal from a green body before sintering or the like wherein the green body is initially heated to a temperature above the melting or flow point of the binder to liquify the binder and, at the elevated temperature, a small portion of the green body is brought into intimate contact with a non-supporting porous body of lower capillarity potential for the liquid binder. The liquid is drawn from all parts of the green body to the region of contact between the porous body and the green body and enters the body of lower capillarity potential preferentially, removing liquid from the green body through the surface of the green body only at said region of contact. The draining is continued with or without further increase in temperature until the green body is opened or becomes permeable.Type: GrantFiled: June 5, 1995Date of Patent: March 18, 1997Assignee: Witec Cayman Patents LimitedInventor: Raymond E.
