GimbalC:

Path: SC/Attitude

% Generate gimbal commands for a gimbal stationkeeping system. 
   Requires two thrusters with double gimbals.

   Inputs
   ------
   a             (n,n) Three axis controller plant matrix in delta form, x = x + a*x
   b             (n,3) Three axis controller input matrix
   c             (3,n) Three axis controller output matrix
   d             (3,3) Three axis controller feedthrough matrix
   psInv         (2,3) Pseudoinverse to convert torque to angle
   x             (n,1) Controller state
   att           (3,1) Attitude errors

   -------
   Outputs
