Patent number: 11860589Abstract: During each of a plurality of iterations, a policy of a controller is updated and at least part of a process is controlled using the updated policy. The updated policy is associated with a performance level of the controller. For each iteration, the updated policy is determined using the associations generated during one or more previous iterations between the policies and the corresponding performance levels of the controller in controlling the at least part of the process, such that the updated policy is optimized to have a highest likelihood of producing a positive change in the performance level of the controller in controlling the at least part of the process rather than optimized to have a highest likelihood of producing a largest positive magnitude of change in the performance level of the controller in controlling the at least part of the process relative to the previous iteration.Type: GrantFiled: January 5, 2021Date of Patent: January 2, 2024Assignee: HONEYWELL INTERNATIONAL INC.Inventors: Daniel Pachner, Vladimir Havlena, Pavel Otta

Patent number: 11796977Abstract: An approach for auto tuning a PID controller that may incorporate determining set-points for controlled variables, obtaining controlled variables from a controlled process module, taking a difference between the set-points and the controlled variable as inputs to a proportional, integral and derivative (PID) controller, calculating a loss or reward from the difference between the controlled variables and the set-points, and achieving set-point tracking. The loss or reward needs to be an increasing or decreasing function of a control error value. Also incorporated may be adding loss or reward components based on controlled variables time difference or control action time difference, which may effect a self-tuned performance of the PID controller.Type: GrantFiled: April 29, 2020Date of Patent: October 24, 2023Assignee: HONEYWELL INTERNATIONAL INC.Inventors: Vladimir Havlena, Daniel Pachner

Patent number: 11687688Abstract: A system and approach for catalyst model parameter identification with modeling accomplished by an identification procedure that may incorporate a catalyst parameter identification procedure which may include determination of parameters for a catalyst device, specification of values for parameters and component level identification. Component level identification may be of a thermal model, adsorption and desorption, and chemistry. There may then be system level identification to get a final estimate of catalyst parameters.Type: GrantFiled: March 19, 2020Date of Patent: June 27, 2023Assignee: Garrett Transportation I Inc.Inventors: Jaroslav Pekar, Gregory Stewart, Ondrej Santin, Daniel Pachner

Patent number: 11619189Abstract: An engine and one or more aftertreatment subsystems integrated into one system for optimization and control. At least one controller may be connected to the engine and the one or more aftertreatment subsystems. The controller may contain and execute a program for the optimization and control of the one system. Controller may receive information pertinent to the engine and the one or more aftertreatment subsystems for the program. The controller may prescribe setpoints and constraints for measured variables and positions of actuators according to the program to aid in effecting the optimization and control of the one system.Type: GrantFiled: September 23, 2021Date of Patent: April 4, 2023Assignee: Garrett Transportation I Inc.Inventors: Jaroslav Pekar, Daniel Pachner

Patent number: 11506138Abstract: An engine system incorporating an engine, one or more sensors, and a controller. The controller may be connected to the one or more sensors and the engine. The one or more sensors may be configured to sense one or more parameters related to operation of the engine. The controller may incorporate an air-path state estimator configured to estimate one or more air-path state parameters in the engine based on values of one or more parameters sensed by the sensors. The controller may have an on-line and an off-line portion, where the on-line portion may incorporate the air-path state estimator and the off-line portion may configure and/or calibrate a model for the air-path state estimator.Type: GrantFiled: September 10, 2019Date of Patent: November 22, 2022Assignee: Garrett Transportation I Inc.Inventors: Daniel Pachner, Dejan Kihas, Lubomir Baramov

Patent number: 11271601Abstract: Systems and methods for pre-distortion pattern recognition are provided. In certain embodiments, the system includes an electronic device that provides an output signal, wherein the electronic device applies distortion to the output signal. The system also includes a pre-distorter that provides an input signal to the electronic device, wherein the pre-distorter applies a pre-distortion to the input signal before the electronic device receives the input signal. Further, the system includes a pre-distorter design block that identifies the distortion from an association between the output signal and a finite set of symbols and updates the pre-distortion based on the association.Type: GrantFiled: October 19, 2020Date of Patent: March 8, 2022Assignee: Honeywell International Inc.Inventors: Daniel Pachner, Vladimir Havlena
