An improved system and apparatus (100) and method for controlling vane angles in a gas turbine engine (10), and more specifically, for correcting vane angle error in a gas turbine engine (10). An active synchronization ring (100) comprises a plurality of micro-actuators (104) coupled to the synchronization ring (64, 102) to correct distortion in the synchronization ring (64, 102). The micro-actuators (104) apply a bending moment to the synchronization ring (64, 102) to cancel or compensate for synchronization ring distortion. The micro-actuators (104) may be controlled open loop or closed loop. Strain sensors (106) measure ring distortion and provide signals to the controller for closed loop control. |
