    Abstract: An unmanned aerial vehicle (UAV) including a winch system, wherein the winch system includes a winch line having a first end that is secured to the payload, and wherein the winch system is controllable to vary the rate of descent of the payload, an inertial measurement unit positioned on the payload or on the first end of the winch line, wherein the inertial measurement unit is configured to measure oscillations of the payload, and a control system configured to (a) receive data from the IMU, (b) determine oscillations of the payload based on the data received from the IMU, and (c) operate the winch system to vary the deployment rate of the winch line so to damp oscillations of the payload.
