Abstract
Systems and methods for estimating an engine event location are disclosed herein. In one embodiment, a control system is configured to receive feedback from at least one vibration sensor coupled to a reciprocating engine, estimate an engine parameter based at least on the feedback and an Empirical Transform Function (ETF), estimate a location of an engine event based on the engine parameter, and adjust operation of the reciprocating engine based at least on the location of the engine event.
Claims20
A system, comprising:
- a controller configured to:
- receive feedback from at least one vibration sensor;
- estimate an engine parameter of a reciprocating engine based at least on the feedback and an Empirical Transform Function (ETF);
- estimate a location of at least one engine event based on the engine parameter, wherein the at least one engine event comprises a first engine event relating to a valve of the reciprocating engine;
- and
- adjust operation of the reciprocating engine based at least on the location of the at least one engine event.

A method, comprising:
- configuring a controller to estimate a location of an engine event in a reciprocating engine, wherein configuring comprises:
- receiving a plurality of vibration signals and a plurality of engine parameter signals;
- determining a plurality of Empirical Transfer Function Estimates (ETFEs) based on Fourier transforms of the plurality of vibration signals and the plurality of engine parameter signals;
- and
- aggregating the plurality of ETFEs to generate an Empirical Transform Function (ETF).
