Automated analysis of non-stationary machine performance

A method for monitoring at least one machine comprising:

• causing at least a first sensor to acquire at least a first non-stationary signal from at least one machine operating in a non-stationary manner during at least one operational time frame, said at least first sensor providing at least a first non-stationary output;
• causing at least a second sensor to acquire at least a second non-stationary signal from said machine during said time frame, said at least second sensor providing at least a second non-stationary output;
• modifying said at least first non-stationary output based on said at least second non-stationary output to extract at least one feature of said first non-stationary output;
• analyzing said at least one feature to ascertain a state of health of said machine;
• and
• performing at least one of a repair operation, maintenance operation and modification of operating parameters of said machine based on said state of health as found by said analyzing.
