摘要： An example feedback control system includes a laser powder bed fusion (L-PBF) platform including a laser. The L-BPF platform is configured to print a target object with the laser. The feedback control system includes a sensing system configured to measure an operative thermal emission index (TEI) emitted during print of the target object by the L-PBF platform. The feedback control system additionally includes a controller communicatively coupled to the sensing system. The feedback control signal is configured to determine an error based on a comparison between a control setpoint and the operative TEI, generate a control signal based on the error, and adaptively adjust a power of the laser during the print of the target object based on the control signal to maintain the control setpoint.
