Definitions

  • This invention relates to satellites and robotic systems, for example controlling the orientation of a satellite using a plurality of control moment gyros (CMG).
  • CMG control moment gyros
  • attitude of an agile spacecraft or satellite is often maintained and adjusted with a control moment gyro array because those devices provide high torque and torque amplification.
  • a typical CMG is a rotating mass suspended on a gimbal with an actuator to rotate it on the gimbal axis, producing torque and accumulating angular momentum.
  • Angular momentum is the integral of torque over time.
  • An array of «>3 CMGs is often used, allowing attitude control with some redundancy.
  • Each CMG has an angular momentum (b) constrained essentially to a plane, the angular momentum vector of the gyro is nearly orthogonal to the gimbal axis.
  • the error in orthogonality is small enough that it does not affect the operation of the CMG, the array of CMGs, or the attitude control of the satellite.
  • the wheel speed of the CMG is essentially constant in most applications, but does not have to be for this invention to work.
  • Q is the result of the cross product Q — ⁇ x t , where ⁇ is the gimbal rate and h is the angular momentum of the rotor, if varying wheel speed is incorporated then
  • An object of the present invention is to significantly increase the speed in reorienting a satellite between two objects by utilizing more of the available angular momentum from the CMGs.
  • the gimbal angle rates are calculated using a new pseudo inverse.
  • the new pseudo inverse prevents the control from becoming unstable when the matrix generated by the Jacobean of the angular momentum with respect to the gimbal angles rank drops to two. Also if a singularity, the rank of the Jacobean drop from three to two, is encountered the solution trajectory passes through the singularity instead of getting caught in the singularity.
  • Fig 2 is a block diagram showing a satellite with CMGs that are rotated to change the satellite's attitude in response to individually produce angular rate signals.
  • Fig. 3 illustrates two possible paths for reorienting between two objects.
  • Fig. 1 shows function blocks that may be implemented through hardware or software, preferably the latter in a computer based satellite control containing one or more signal processors programmed to produce output signals to control CMGs on the satellite as explained hereafter. Fundamentally the process is shown for a single signal path between two points, but it should be understood that single lines represent vector data which is 3 dimensional for the satellite attitude, attitude rate and torque, and n dimensional for the signals related to the n CMGs.
  • the control scheme shown in Fig. 1 is used to pan or rotate the satellite on its axis from the line of sight view of an object A to a line of sight view of object B Fig 3.
  • a typical closed loop control follows an eigen axis rotation path "old" by controlling the CMGs based on the actual (determined from the attitude determination system ADS in Fig. 3) and desired path attitude.
  • the invention is not constrained to follow an eigen axis path as will be explained.
  • the desired satellite attitude at input 10 presented as Euler angles, quaternions, Gibbs parameters, or some other convenient way of describing the attitude of a satellite, compared at 14 with actual attitude at input 12 generated by the Inertial Measurement Unit (IMU) 56 or some other method for determining satellite attitude.
  • the attitude error 16 is used by the attitude control 18 to generate a desired body acceleration, CO at
  • the modified pseudo inverse 36 is used to calculate the close loop gimbal rates, A 42, according to the following:
  • ⁇ c A T ( P A A T + k I ) " ' P h c 36.
  • the added term kl is to keep the equation from becoming indeterminate as the solution trajectory passes through internal singularities, that would be inescapable if this control was not used.
  • the weighting matrix P is used to escape any singularity that is encountered. In order to do this P
  • the CMG array 48 responds to the gimbal rate command 42.
  • the CMG array 48 movement produces torque h 50 on the satellite 52.
  • the satellite motion ⁇ 54 is detected by the attitude sensors 56.
