System for turbomachine vane control

A gas turbine system, comprising:

• a compressor having a plurality of vanes disposed circumferentially about an axis of the compressor;
• a first actuator configured to adjust a pitch of the plurality of vanes;
• a second actuator configured to adjust the pitch of the plurality of vanes;
• a first electric motor configured to drive the first actuator;
• a second electric motor configured to drive the second actuator;
• and
• a control system comprising the first and second electric motors, wherein the control system is configured to control the first and second actuators independently in coordination with one another via first and second motor controllers, respectively, and wherein the control system is configured to control the first and second actuators based on a first position feedback from the first actuator and a second position feedback from the second actuator, and wherein the control system is configured to control the first and second actuators independently in coordination with one another, via the first and second motor controllers, to help achieve a targeted flow and pressure profile in the compressor.

An actuator system, comprising:

• a first electric motor;
• a second electric motor
• a first actuator configured to be driven by the first electric motor and to adjust a first pitch of a plurality of inlet guide vanes of a compressor;
• a second actuator configured to be driven by the second electric motor to adjust a second pitch of a plurality of variable stator vanes;
• and
• at least one controller comprising memory and a processor configured to execute instructions to control the first electric motor and the second electric motor based on sensor feedback relating to operation of the compressor.
