-/**
- * @file fw_pos_control_l1_main.c
- * Implementation of a generic position controller based on the L1 norm. Outputs a bank / roll
- * angle, equivalent to a lateral motion (for copters and rovers).
- *
- * Original publication for horizontal control class:
- *    S. Park, J. Deyst, and J. P. How, "A New Nonlinear Guidance Logic for Trajectory Tracking,"
- *    Proceedings of the AIAA Guidance, Navigation and Control
- *    Conference, Aug 2004. AIAA-2004-4900.
- *
- * Original implementation for total energy control class:
- *    Paul Riseborough and Andrew Tridgell, 2013 (code in lib/external_lgpl)
