3 1 14 Speed controller bandwidth Speed controller bandwidth, in Hz. Higher values result in faster speed and current rise times, but may result in overshoot and higher current consumption. For fixed-wing aircraft, this value should be less than 50 Hz; for multirotors, values up to 100 Hz may provide improvements in responsiveness. Hertz 10 250 Reverse direction Motor spin direction as detected during initial enumeration. Use 0 or 1 to reverse direction. 0 1 Speed (RPM) controller gain Speed (RPM) controller gain. Determines controller aggressiveness; units are amp-seconds per radian. Systems with higher rotational inertia (large props) will need gain increased; systems with low rotational inertia (small props) may need gain decreased. Higher values result in faster response, but may result in oscillation and excessive overshoot.

For electric aircraft this will normally be set to zero, but can be set to a small non-zero value if a folding prop is fitted to prevent the prop from folding and unfolding repeatedly in-flight or to provide some aerodynamic drag from a turning prop to improve the descent rate. For aircraft with internal combustion engine this parameter should be set for desired idle rpm. 0.0 1.0 norm 2 0.01 modules/fw_pos_control_l1 Idle throttle This is the minimum throttle while on the ground For aircraft with internal combustion engine this parameter should be set above desired idle rpm. 0.0 0.4 norm 2 0.01 modules/fw_pos_control_l1 Throttle limit value before flare This throttle value will be set as throttle limit at FW_LND_TLALT, before aircraft will flare. 0.0 1.0 norm 2 0.01 modules/fw_pos_control_l1 Climbout Altitude difference If the altitude error exceeds this parameter, the system will climb out with maximum throttle and minimum airspeed until it is closer than this distance to the desired altitude.

This allows to limit the maximum pitch angle during a bungee launch (make the launch less steep). 0.0 45.0 deg 1 0.5 lib/launchdetection Cruise Airspeed The fixed wing controller tries to fly at this airspeed. 0.0 40 m/s 1 0.5 modules/navigator Minimum Airspeed If the airspeed falls below this value, the TECS controller will try to increase airspeed more aggressively. 0.0 40 m/s 1 0.5 modules/fw_pos_control_l1 Maximum Airspeed If the airspeed is above this value, the TECS controller will try to decrease airspeed more aggressively. 0.0 40 m/s 1 0.5 modules/fw_pos_control_l1 Maximum climb rate This is the best climb rate that the aircraft can achieve with the throttle set to THR_MAX and the airspeed set to the default value. For electric aircraft make sure this number can be achieved towards the end of flight when the battery voltage has reduced. The setting of this parameter can be checked by commanding a positive altitude change of 100m in loiter, RTL or guided mode. If the throttle required to climb is close to THR_MAX and the aircraft is maintaining airspeed, then this parameter is set correctly. If the airspeed starts to reduce, then the parameter is set to high, and if the throttle demand required to climb and maintain speed is noticeably less than FW_THR_MAX, then either FW_T_CLMB_MAX should be increased or FW_THR_MAX reduced. 1.0 15.0 m/s 1 0.5 modules/fw_pos_control_l1 Minimum descent rate This is the sink rate of the aircraft with the throttle set to THR_MIN and flown at the same airspeed as used to measure FW_T_CLMB_MAX. 1.0 5.0 m/s 1 0.5 modules/fw_pos_control_l1 Maximum descent rate This sets the maximum descent rate that the controller will use. If this value is too large, the aircraft can over-speed on descent. This should be set to a value that can be achieved without exceeding the lower pitch angle limit and without over-speeding the aircraft. 2.0 15.0 m/s 1 0.5 modules/fw_pos_control_l1 TECS time constant This is the time constant of the TECS control algorithm (in seconds).

Increase to add damping to correct for oscillations in speed and height. 0.0 2.0 1 0.1 modules/fw_pos_control_l1 Integrator gain This is the integrator gain on the control loop. Increasing this gain increases the speed at which speed and height offsets are trimmed out, but reduces damping and increases overshoot. 0.0 2.0 2 0.05 modules/fw_pos_control_l1 Maximum vertical acceleration This is the maximum vertical acceleration (in m/s/s) either up or down that the controller will use to correct speed or height errors. The default value of 7 m/s/s (equivalent to +- 0.7 g) allows for reasonably aggressive pitch changes if required to recover from under-speed conditions. 1.0 10.0 m/s/s 1 0.5 modules/fw_pos_control_l1 Complementary filter "omega" parameter for height This is the cross-over frequency (in radians/second) of the complementary filter used to fuse vertical acceleration and barometric height to obtain an estimate of height rate and height. Increasing this frequency weights the solution more towards use of the barometer, whilst reducing it weights the solution more towards use of the accelerometer data. 1.0 10.0 rad/s 1 0.5 modules/fw_pos_control_l1 Complementary filter "omega" parameter for speed This is the cross-over frequency (in radians/second) of the complementary filter used to fuse longitudinal acceleration and airspeed to obtain an improved airspeed estimate. Increasing this frequency weights the solution more towards use of the airspeed sensor, whilst reducing it weights the solution more towards use of the accelerometer data. 1.0 10.0 rad/s 1 0.5 modules/fw_pos_control_l1 Roll -> Throttle feedforward Increasing this gain turn increases the amount of throttle that will be used to compensate for the additional drag created by turning. Ideally this should be set to approximately 10 x the extra sink rate in m/s created by a 45 degree bank turn. Increase this gain if the aircraft initially loses energy in turns and reduce if the aircraft initially gains energy in turns. Efficient high aspect-ratio aircraft (eg powered sailplanes) can use a lower value, whereas inefficient low aspect-ratio models (eg delta wings) can use a higher value. 0.0 20.0 1 0.5 modules/fw_pos_control_l1 Speed <--> Altitude priority This parameter adjusts the amount of weighting that the pitch control applies to speed vs height errors. Setting it to 0.0 will cause the pitch control to control height and ignore speed errors. This will normally improve height accuracy but give larger airspeed errors. Setting it to 2.0 will cause the pitch control loop to control speed and ignore height errors. This will normally reduce airspeed errors, but give larger height errors. The default value of 1.0 allows the pitch control to simultaneously control height and speed. Note to Glider Pilots - set this parameter to 2.0 (The glider will adjust its pitch angle to maintain airspeed, ignoring changes in height). 0.0 2.0 1 1.0 modules/fw_pos_control_l1 Pitch damping factor This is the damping gain for the pitch demand loop.
