1. A method for controlling two or more linear generators, the method comprising:
determining, using control circuitry, a desired phase offset between operation of a first linear generator and a second linear generator;
determining, during operation, an actual phase offset between the first linear generator and the second linear generator; and
modifying, using the control circuitry, operation of at least one of the first linear generator or the second linear generator to achieve the desired phase offset based on the actual phase offset.
