Roll Rate

File: In sw/airborne/fw_h_ctl.c we define the roll rate loop:

float cmd = throttle_dep_pgain * ( err + h_ctl_roll_rate_igain * roll_rate_sum_err / H_CTL_ROLL_RATE_SUM_NB_SAMPLES + h_ctl_roll_rate_dgain * d_err);

Note that the roll Pgain is variable with throttle and multiplies through the entire equation affecting the I and D terms as well for ease of tuning.

Established in 1992 in the state of Maine, USA, Control Engineering rapidly gained a reputation for the ability to design, build, reverse engineer, and repair electronic circuits. In 1996 we were commissioned by The Hinckley Company to design and manufacture the Jetstick™ for their famous "Picnic Boat™". Since then, we have designed systems for numerous companies and individual owners, installing our controls on boats from 16 feet to ship class (200 feet). In the summer of 2007, we relocated to our current location in Palm Coast, Florida.
Control Engineering manufactures most control circuits in our on-site facility.

That leaves my third, second, and top-most choices still to go. So here they are:

• Volumes of scans of IBM and paper company specifications and test procedures
• Many references to TAPPI (Technical Association of the Pulp and Paper Industry) standards.
• Hosted by the IBM 1401 Restoration Project of the Computer History Museum
• The host domain is actually Ed Thelen's Nike Missile Web Site
