Actuator and cable dynamics
===========================
Subsystem of APILOT1, APILOT2, and APILOT3.
This subsystem contains the dynamics of the actuators and cables
for ailerons, elevator, and rudder channels. In the case of the
'Beaver' aircraft, these dynamics are modelled as linear state-
space blocks. Before starting a new simulation, the state matri-
ces Aail, Bail, Cail, Dail, Aelv, Belv, Celv, Delv, and Arud,
Brud, Crud, and Drud must be loaded into the MATLAB workspace.
These matrices can be obtained from the files FCS35.DAT,
FCS45.DAT, or FCS55.DAT, which contain the state matrices for
V = 35 m/s, V = 45 m/s, and V = 55 m/s, respectively. Choose
the set which best fits your desired airspeed; in general
FCS45.DAT gives good results.

autopilot simulation system.
