Hoist System and Process for Sway Control

A method of controlling an aircraft hoist system, comprising:

• implementing hoist equipment in an aircraft, the hoist equipment including a motor, a cable, and a hook portion;
• obtaining measurements from at least one sensor by measuring with the at least one sensor at least one of following:
• a load measurement, a cable position movement measurement, a cable movement measurement, an aircraft movement measurement, and an airspeed measurement;
• analyzing the measurements with a processor from the at least one sensor;
• determining motor control signals with the processor for controlling the motor based on an analysis of the measurements from the at least one sensor to reduce sway and/or oscillations of the cable while lifting a load;
• and
• controlling the motor with the processor to lift the load with the cable based on the determined motor control signals,
• wherein the at least one sensor comprises at least one of the following:
• a load measurement sensor, a cable movement measurement sensor, a cable position measurement sensor, an aircraft movement measurement sensor, and an airspeed measurement sensor.
