20100017094 | CONFIGURABLE AUTOMOTIVE CONTROLLER - An engine control unit having a one-time integration of a model predictive control template via a potentially long software process. Changes to the control structure may subsequently be made via a calibration dataset connected to the engine control unit without incurring the potentially long and laborious software process of implementing the template of other approaches in the related art. | 01-21-2010 |
20100305719 | METHOD AND SYSTEM FOR COMBINING FEEDBACK AND FEEDFORWARD IN MODEL PREDICTIVE CONTROL - A method and system for combining a feedback control and a feedforward control in a linear MPC to minimize effect of model uncertainty. An externally computed feedforward signal, which is more accurate and reliable, can be utilized in association with the MPC. A steady state relation between system parameters can be determined in order to compute the feedforward signal for a set of actuators associated with a non-linear system. A feedback MPC controller can then be designed. A state observer can be configured as an unknown input observer to estimate the effect of the feedforward signal. A strategy for manipulating the constraints of the MPC feedback signal can be implemented. A resulting control action for the actuators can be provided as a sum of corresponding feedback and feedforward signal while ensuring the constraints satisfaction. | 12-02-2010 |

20120271528 | METHODS AND SYSTEMS FOR THE DESIGN AND IMPLEMENTATION OF OPTIMAL MULTIVARIABLE MODEL PREDICTIVE CONTROLLERS FOR FAST-SAMPLING CONSTRAINED DYNAMIC SYSTEMS - Methods and systems for the design and implementation of optimal multivariable MPC controllers for fast-sampling constrained dynamic systems utilizing a primal-dual feasibility approach and/or a graph approach. The primal-dual feasibility approach can compute and store matrices defining constraints of quadratic programming problems in an off-line part in order to calculate vectors of Lagrange multipliers and an optimizer. Then primal-dual feasibility can be checked in an on-line part using the Lagrange multipliers and the optimizer can provide a unique optimal solution for the constrained dynamic system. The graph approach can compute and store the matrices and the vectors, and also prepare and store a structure of directed graph in off-line part. An optimizer for a given parameter vector can be determined in on-line part using the directed graph, the matrices and the vectors. | 10-25-2012 |

20080201850 | Positioning platform for prone breast imaging - Embodiments include a platform allowing the female breast to be imaged by PET/CT, SPECT, and/or other modalities, while the patient is lying in the prone position. In some embodiments, a cushioned base may support the patient's torso, and articulating head and arm rests may extend from the base. A pair of open-sided lateral openings in the base allows the patient's breasts to hang independently. The articulating head and arm rests may be lockable into a fixed position and may be unlocked and returned to the original locked position. The base may be constructed of a composite material and covered with a cushioning material, with an optional adjustable, pneumatic layer in between. The cushioning material may be form-molded foam or other material. The platform may be attached to an existing PET gantry table via attachment means that allows the platform to be removed and afterward identically repositioned with respect to the gantry table for subsequent imaging. | 08-28-2008 |
