Step 1: electricity of the measurement unmanned plane when executing various flare maneuvers and keeping flight stability state adjusts input voltage
Value and corresponding throttle value.(battery non-present unmanned plane field by taking the dedicated lithium battery of a kind of aircraft on the market as an example
Mainstream battery is only used as test in the present invention), fully charged rear virtual voltage is probably in 12.7V or so, with lithium battery
Using electric discharge, cell voltage can be gradually reduced, and dropped to 11.3V or so to stop supply terminals, used at this time for protection lithium battery
Service life and terminate its power supply, through use the multiple flight test of above-mentioned lithium battery, determined its stabilization take off after voltage and throttle value
(voltage value about 12V).
Step 2: connecting the voltage regulation unit of adjustable voltage between the battery and electricity of unmanned plane are adjusted；
It should be noted that it will be appreciated by those skilled in the art that, voltage regulation unit can using it is in the prior art other
Structure comprising but be not limited to using following two structure: a kind of structure of voltage regulation unit is as shown in Figure 1 comprising single-chip microcontroller,
Sepic chopper circuit, optically coupled circuit and sample circuit；Sepic chopper circuit connect optically coupled circuit, sample circuit and
The battery and electricity of unmanned plane are adjusted, and optically coupled circuit connects single-chip microcontroller and Sepic chopper circuit, and sample circuit connects Sepic copped wave
Circuit and single-chip microcontroller, single-chip microcontroller are powered by the system power supply circuit of unmanned plane and are connected to the winged control of unmanned plane to obtain current fly
Row action message；Unmanned plane is executed into various flare maneuvers and electricity corresponding to flight stability state is kept to adjust input voltage value pre-
Be located in single-chip microcontroller, Sepic chopper circuit is exported the voltage value adjusted to electricity and feeds back to single-chip microcontroller by sample circuit, single-chip microcontroller by its
Corresponding pwm control signal is exported compared with the preset voltage value corresponding with current flight movement and according to comparison result control,
The pwm control signal controls being switched off and on for Sepic chopper circuit switching tube after optically coupled circuit improves amplitude
System exports the voltage adjusted to electricity according to the currently performed flare maneuver control Sepic chopper circuit of unmanned plane to realize
So that the electricity of input voltage value and preset unmanned plane that electricity is adjusted when executing the flare maneuver and keeping flight stability state is adjusted
Input voltage value is consistent.
Another structure of voltage regulation unit are as follows: including Sepic chopper circuit, optically coupled circuit and sample circuit；Sepic is cut
Wave circuit connects the battery of optically coupled circuit, sample circuit and unmanned plane and electricity is adjusted, and optically coupled circuit connects flying for unmanned plane
Control and Sepic chopper circuit, sample circuit connect the winged control of Sepic chopper circuit and unmanned plane；Unmanned plane is executed into various fly
Row acts and holds electricity corresponding to flight stability state and input voltage value is adjusted to be preset in the winged control of unmanned plane, and sample circuit will
Sepic chopper circuit, which is exported, feeds back to winged control to the voltage value of electricity tune, flies control for it and acts corresponding preset with current flight
