Play the calculating of frequency.
The angular transducer 12 can convert angle signal to the voltage signal of 0~5V, by A/D converter by mould
Analog quantity is converted into digital quantity and uses for measuring and calculating module.
It is poor by the angle work to six points before and after certain point to swat frequency, calculates instantaneous angular frequency, thus calculates one
A frequency for swatting the period.
The specific method is as follows:
The instantaneous angular frequency of i-th moment point is denoted as ωiIt indicates are as follows:
Ai-3~Ai+2Indicate that the angle value of i-th -3~i+2 moment point, f indicate sample frequency, calculate instantaneous angular frequency
ωiAfterwards, can be swatted according to the angular frequency a cycle (above flutter and under flutter maximum angular and be denoted as θmax) time, Jin Erji

Shaft hole matching time control module is given, it is poor that shaft hole matching time control module makees current angular with the conversion angle received
Value calculates the time that starting fixed shaft hole cooperates control module further according to frequency is currently swatted.
Its calculation method are as follows:
In formula (4), tstartFor the delay time for starting shaft hole matching, tkIt is rotated for trigonometric expression fixing axle 10 from initial angle
Time needed for fixed angles, θg、θcPredetermined angular and current airfoils angle, ω when respectively indicating fixed-wing are indicated when anterior angle speed
Degree.
After delay time reaches, the operation of shaft hole matching control module is directly fixed；Firstly, fixed shaft hole cooperation control
Module control initial angle is changed to fixed angles, i.e. 10 bottom of trigonometric expression fixing axle is rotated around cabinet 9 to trigonometric expression fixing axle 10
Connecting shaft 16 can be slided along the sliding slot 18 on canine tooth wheel face, and axis hole (connecting shaft 16 and matching hole) starts to cooperate at this time.
Then, whether status check module detection axis hole successfully cooperates, and wing amplitude calculates module measurement wing angle simultaneously
Judge whether it is consistent with the conversion angle received, if cooperated successfully, motor control module controls driving motor 3
It shuts down rapidly, completes conversion.
Cooperate successfully includes following three kinds of situations:
If as shown in Fig. 2, when trigonometric expression fixing axle is fixed to position shown in matching hole 11A, the fixation of wing angle is about
30 °, shaft hole matching success achievees the purpose that lock gear wheel 2.
If wing angle is fixed about as shown in figure 3, when trigonometric expression fixing axle is fixed to position shown in matching hole 11B-
5 °, shaft hole matching success achievees the purpose that lock gear wheel 2.
If wing angle is fixed about as shown in figure 4, when trigonometric expression fixing axle is fixed to position shown in matching hole 11C-
15 °, shaft hole matching success achievees the purpose that lock gear wheel 2.
If cooperation is unsuccessful, control signal is back to fixed shaft hole cooperation control module, continues to operate by original process,
Until shaft hole matching success.
Landing phases, the signal that control system receives are that fixed-wing is converted to flapping mode signal, fixed shaft hole cooperation
Control module passes through control fixed angles first and is changed to initial angle, to cancel the cooperation of connecting shaft 16 Yu matching hole；It is specific to execute
Mode are as follows: 10 bottom end of trigonometric expression fixing axle turns to 10 liang of connecting shafts 16 of trigonometric expression fixing axle and 2 thickness of gear wheel around cabinet 9
It is identical, cancel the cooperation of connecting shaft 16 Yu matching hole with this.
Then, whether status check module detection axis hole successfully discharges, if discharged successfully, driving motor control is opened rapidly
Dynamic driving motor 3, pinion gear and gear wheel 2 make gear motion, and gear wheel 2 drives crank 4A (4B) to make circumference turnover movement, into
And transmission rocking bar 5A (5B) is driven to swing；It is driven rocking bar 5A (5B) and wing main spar 6A (6B) is driven by rolling bearing 7A (7B)
It is swatted up and down around rotating base 8A (8B), completes conversion.
If release is unsuccessful, control signal is back to fixed shaft hole cooperation control module, continues to operate by original process,
Until axis hole discharges successfully.
The application can be realized flapping wing take off, fixed-wing cruise, to reach in small place, the quick landing of complex condition,
It gets rid of the dependence to dedicated landing runway, in addition has both the advantage of fixed wing aircraft again in cruising phase, i.e., high-efficient, cruise speed
Degree is fast；It is different with completion to adapt to different flight environment of vehicle that the angle of fixed-wing can neatly be changed in cruising phase simultaneously
Aerial mission.
