  • Control system for stabilizing a single line suspended mass in yaw
    Patent number: 8938325
    Abstract: A control system and method for stabilizing a suspended mass in yaw on a single cable utilizing thrusters. In one embodiment rate gyroscopes are placed on the load and the thrusters are utilized so that the angular position converges to a selected or given angular position. The system implementation includes a pure loading case where cable spring and damping parameters are estimated as constants for the entire lift. The system implementation also includes a multi-height manipulation case where cable spring and damping parameters are determined from a look up table based on cable length.
