Abstract
A mobile work machine includes a sensor configured to generate a sensor signal indicative of operation of the mobile work machine, a machine performance detection system configured to receive the sensor signal, generate a topological representation of the sensor signal, and determine a machine performance characteristic based on the topological representation relative to a reference model, and a control system configured to generate a control signal to control the mobile work machine based on the machine performance characteristic.

A mobile work machine comprising:
- a sensor configured to generate a sensor signal indicative of operation of the mobile work machine;
- a machine performance detection system configured to:
- receive the sensor signal;
- generate a topological representation of the sensor signal;
- and
- determine a machine performance characteristic based on the topological representation relative to a reference model;
- and
- a control system configured to generate a control signal to control the mobile work machine based on the machine performance characteristic.
A method performed by a computing system associated with a mobile work machine, the method comprising:
- receiving, from a sensor associated with the mobile work machine, a sensor signal indicative of operation of the mobile work machine;
- generating a topological representation of the sensor signal;
- determining a machine performance characteristic based on the topological representation relative to a reference model;
- and
- generating a control signal to control the mobile work machine based on the machine performance characteristic.
A computing system for a mobile work machine, the computing system comprising:
- at least one processor;
- and
- memory storing instructions executable by the at least one processor, wherein the instructions, when executed, cause the computing system to:
- receive a sensor signal that defines a time series of feature values;
- generate a topological representation that models a shape of the sensor signal over time by applying a topological data analysis algorithm to the time series of feature values;
- determine a machine performance characteristic based on the topological representation relative to a reference model;
- and
- generate a control signal to control the mobile work machine based on the machine performance characteristic.
