Abstract
Control of a turbocharger of a power system is disclosed. A controller may receive a desired value for a parameter of an engine. The controller may receive an operating value of the parameter. The controller may set, based on the desired value and the operating value, a position of an intake throttle valve of the engine to control air flow through a turbocharger of the engine.
Claims20
A control system for operating an engine, comprising:
- a memory;
- and
- a processor, communicatively coupled to the memory, configured to:
- receive a desired value for a parameter of the engine;
- receive, from a sensor, an operating value of the parameter of the engine;
- and
- set, based on the desired value and the operating value, a position of an intake throttle valve of the engine to control air flow through a turbocharger of the engine.
4 more elements
A method, comprising:
- identifying, using an optimization model, a desired value for a parameter of an engine;
- detecting an operating value of the parameter of the engine based on one or more measurements received from a sensor system;
- determining, using an electronic control module, that a difference between the desired value and the operating value is outside of a threshold range;
- and
- adjusting, using an electronic control module, based on the difference, a position of an intake throttle valve to control a rotational speed of a turbocharger of the engine to reduce the difference between the desired value and the operating value.
2 more elements
A power system comprising:
- an engine that includes a turbocharger and an intake throttle valve;
- a sensor system;
- and
- an electronic module configured to
- identify a desired value for a parameter of the engine;
- detect, based on a measurement from the sensor system, an operating value of the parameter of the engine;
- and
- adjust, based on the desired value and the operating value, a position of the intake throttle valve to control a rotational speed of the turbocharger.
