Controlling a turbocharger system

A method of controlling a turbocharger system that comprises a turbine, a fluid source comprising a pressurized fluid that is fluidly coupled to the turbine, at least one input valve fluidly coupled between the fluid source and an input of the turbine, at least one bypass valve fluidly coupled between the fluid source and an output of the turbine, and a rotating machine, the method comprising:

• determining a level of the pressurized fluid in the fluid source;
• determining at least one of a flow rate or a pressure of a working fluid moved by the rotating machine;
• and
• based on at least one of the determined fluid source level and the at least one of the determined flow rate or pressure, operating the at least one input valve and the at least one bypass valve to change an operating state of the turbine from a first operating state to a second operating state,
• wherein the first operating state comprises an initialization state and the second operating state comprises a stabilization state, and operating the at least one input valve and the at least one bypass valve to change an operating state of the turbine from the first operating state to the second operating state comprises:
• determining that the at least one input valve is in an automatic mode,
• determining that an output recycle valve of the rotating machine is closed, and
• switching the turbine from the initialization state to the stabilization state, and
• wherein the method further comprises operating the at least one input valve and the at least one bypass valve to change the operating state of the turbine from the second operating state to a third operating state.

A computer-implemented method of controlling a turbocharger system, the computer-implemented method comprising:

• identifying, with a computing system that comprises one or more hardware processors, one or more operating conditions of a turbocharger system that comprises a turbine, a fluid source comprising a pressurized fluid that is fluidly coupled to the turbine, at least one input valve fluidly coupled between the fluid source and an input of the turbine, at least one bypass valve fluidly coupled between the fluid source and an output of the turbine, and a rotating machine;
• determining, with the computing system, a level of the pressurized fluid in the fluid source based on at least one of the one or more identified operating conditions;
• determining, with the computing system, at least one of a flow rate or a pressure of a working fluid moved by the rotating machine based on at least another one of the one or more identified operating conditions;
• and
• based on at least one of the determined fluid source level and the at least one of the determined flow rate or pressure, operating, with the computing system, the at least one input valve and the at least one bypass valve to change an operating state of the turbine from a first operating state to a second operating state,
• wherein the first operating state comprises an initialization state and the second operating state comprises a stabilization state, and operating the at least one input valve and the at least one bypass valve to change an operating state of the turbine from the first operating state to the second operating state comprises:
• determining, with the computing system, that the at least one input valve is in an automatic mode,
• determining, with the computing system, that an output recycle valve of the rotating machine is closed, and
• switching, with the computing system, the turbine from the initialization state to the stabilization state, and
• wherein the method further comprises operating, with the computing system, the at least one input valve and the at least one bypass valve to change the operating state of the turbine from the second operating state to a third operating state.
