1. A system for torch control for achieving ignition in a turbomachine, the system comprising:
one or more torches;
at least one torch active pressure control (TAPC) system in fluid communication with at least one of the one or more torches, wherein the TAPC system is configured to set a fuel pressure of fuel that is supplied to the at least one torch; and
a controller configured to actuate the at least one TAPC system:
to modulate the fuel pressure that is supplied to the at least one torch, according to a modulation profile that traverses a range of fuel pressures thereby producing a range of flame heights of the at least one torch, and
to shut off flow of the fuel to the one or more torches after a lightoff of the turbomachine.
