Patent GB-2565059-A (GB)
Title: Induction motor control
Inventor: JIAN LI
IPC: H02P23/08
Filed: 2017-07-28
Abstract: A method of slowing an induction motor comprising applying an alternating braking voltage Vbr to the stator, the braking voltage having a frequency that provides a negative slip of less than -1. The braking voltage may have a frequency that provides a slip of between -3 and -30. The frequency of the braking voltage may be: less than half of the reduced operating frequency; varied in proportion to the current operating frequency to obtain a desired slip that achieves a desired power dissipation inside the motor; varied to obtain a desired current generated by the motor; increased when a current generated by the motor is greater than a desired current; decreased when a current generated by the motor is less than a desired current. The magnitude of the braking voltage may be: varied based on the current operating frequency of the rotor; varied to obtain a desired current generated by the motor; reduced when a current generated by the motor is greater than a desired current; increased when a current generated by the motor is less than a desired current. A reduced driving voltage, which is lower in magnitude than the braking voltage, may be applied concurrently with the braking voltage. When a desired rotational frequency is achieved the alternative braking voltage may be removed and the magnitude of the alternating drive voltage increased.

Title: Agile satellite target decomposition method and system based on push-broom trajectory
Inventor: RENJIE HE
IPC: G01C11/00
Filed: 2017-11-27
Abstract: When a target is in range of a satellite, a minimum swath width (eta) is calculated to account for attitude changes of the satellite, and represent the width which is certain to be within targeting range of the satellite. A push-broom trajectory, which represents the projection of the satellites path onto the imaged surface, is calculated using the minimum strip width and the boundaries of the targeted region. The push-broom trajectory and the minimum strip width are then substituted into a model, which uses a conjugate quaternion-based coordinate transformation, to calculate coordinates of the four vertices of the strip. To ensure coverage of the entire region by overlapping strips, the planes containing the push-broom trajectories may be generated recursively. The final strip may be corrected, by shortening it and/or moving it inwards, to avoid redundancies in detection. Strips to cover linear targets may be obtained by fitting using forward matching.
