Batch Linearization

The gains of the flight control system are typically scheduled as a function of alpha and

beta, see Part 2 (“Angular Rate Control in the HL-20 Autopilot” (Control System Toolbox))

for more details. To tune these gains, you need linearized models of the HL-20 airframe at

the 40 trim conditions. Use linearize to compute these models from the trim operating

conditions ops.
