For the relative position of fiducial cameras, and obtained according to the positional information after the positional information of unmanned plane relative vehicle landing point
The airborne control subsystem of unmanned plane is sent to by the first wireless data transmission module.
The partial routine realizes that development environment is windows7 systems in navigational computer, and exploitation software is
Microsoft Visual Studio 2010.Specially:If the camera in wherein a set of vision processing system is origin O,
Camera in another set of vision processing system is point O1, with OO1For x-axis, it is straight up y-axis, sets up the right side as shown in Figure 3
Hand rectangular coordinate system M.The number of revolutions that navigational computer passes through the data processing chip Arduino mini pro motors passed back
Count value, calculates the deflection angle of yaw motor and pitching motor in two sets of vision processing systems;If the cloud of camera at origin
Platform yaw angle is α1, the angle of pitch be β1, O1The head yaw angle of camera is α at point2, the angle of pitch be β2.Then in known OO1=s
In the case of, the coordinate (x in rectangular coordinate system of the unmanned plane at point A can be calculated0, y0, z0):
(formula 1)
Station-keeping data of the unmanned plane relative to fiducial cameras obtained according to formula 1.If the level point of unmanned plane
For OO1Midpoint, then using the midpoint as origin, set up rectangular coordinate system N, thirdly axle respectively three axles corresponding with M coordinate systems put down
Go and direction is identical, then under rectangular coordinate system N, unmanned plane relative vehicle landing pointPositional information for (x, y,
Z) it is:
(formula 2)
Positional information (x, y, z) data in formula 2 are sent to machine by navigational computer by the first wireless data transmission equipment
Carry control subsystem.Airborne control subsystem realizes that many rotor unmanned helicopter landing comprise the following steps:
Step (21), data acquisition:The sensor assembly of unmanned plane gathers the attitude data for obtaining unmanned plane, height in real time
Data are detected, and the data collected are sent to flight-control computer;Meanwhile, airborne control subsystem is wireless by second
The positional information that data transmission equipment receives unmanned plane relative vehicle landing point is (x, y, z), and the relative position information (x, y, z) is
The tracking error data of each control rate.Wherein, the relative velocity data is the speed of relative automobile, according to relative position information meter
Calculate and obtain.
Step (22), data calculation:The sensing data received is calculated attitude data, height by flight-control computer
Degrees of data, then calculates the speed of many rotor unmanned helicopter relative vehicles according to the real time data of positional information (x, y, z)
Data;Then by the speed data of the altitude information calculated, attitude data, station-keeping data and relative vehicle and expectation
Data are compared, and obtain error information.Wherein, expected data includes desired position data, altitude information, also desired
Speed, attitude data.
Step (23), control law is resolved:Error information and the unmanned aerial vehicle (UAV) control rule obtained according to step (22), which is calculated, to be held
The controlled quentity controlled variable of row mechanism;Wherein, unmanned aerial vehicle (UAV) control rule include attitude control law, height-holding control law, horizontal direction control law and
Speed control rate.
For unmanned plane be a under-actuated systems and the characteristics of be difficult to control to, using classical PID controller come to many
Heligyro is controlled, and control system block diagram is as shown in Figure 4:
(1) attitude control law
The axis attitude of unmanned plane three keeps the control law of system to be all made up of attitude angular rate and angular displacement feedback, uses this
Planting electrical feedback mode improves the stability of unmanned plane.For vertical/horizontal gesture stability and Heading control, attitude keeps system
Controlled using classical PID.Attitude keeps system to be in innermost ring, all needs to connect in whole flight course.
Attitude keeps the attitude angle a reference value in loop to refer to that unmanned plane matches somebody with somebody level values under hovering mode, is obtained by experiment
, generally differ and be set to zero;The actual measured value of attitude is that attitude data is measured by six airborne axle attitude transducers
's.The difference of actual value and a reference value is error, here it is the source of error feedback control;For attitude keeps loop,
Two errors of attitude angular velocity and attitude angular displacement can be obtained.
The attitude of unmanned plane pitch channel keeps the control law to be:
The attitude of unmanned plane roll passage keeps the control law to be:
The attitude of unmanned plane jaw channel keeps the control law to be:
Wherein, Δ δe、Δδa、ΔδrRespectively pitching, roll, the controlled quentity controlled variable of yaw direction, Δ θ and Δ θ ' bow respectively
The error of elevation angle error and rate of pitch, Δ φ and Δ φ ' are the error of roll angle error and roll angular speed, Δ ψ respectively
It is the error of driftage angle error and yaw rate respectively with Δ ψ ',WithAs pitching angular displacement, the angle of pitch position
The coefficient of allochthonous deposit point and pitch rate,WithAs roll angular displacement, roll angular displacement integration and rolling angle rate
Coefficient,WithAs yaw displacement, yaw displacement integration and yawrate coefficient.
So that the attitude of pitch channel keeps control law as an example,WithConstitute a kind of PID control rule.ΔδeTurn
The pwm signal of correspondence ratio is turned to, is acted on aviation mechanism.When unmanned plane is bowed, corresponding control law can make front two
Individual motor speed increase produces a nose-up pitching moment, allows unmanned plane to come back, to offset the trend bowed, and unmanned plane is kept flat
Weighing apparatus, vice versa.WithThe acquisition of three parameters is the scheme for taking " first according to modelling, adjustment is tested again "
What debugging came out, it is therefore an objective to make the fast response time of unmanned plane, overshoot small.
It is demonstrated experimentally that this control program is simple and easy to apply, effect is notable so that unmanned plane, which possesses certain anti-air-flow, to be done
The ability disturbed.
(2) height-holding control law
Change the method for height, that is, change motor speed, so as to improve lift.Highly control is that nobody is straight by many rotors
The positional information z risen under machine rectangular coordinate system N adjusts the size of motor speed with the difference DELTA z of Desired Height 0.Highly control
Controlled using classical PID.
The height of landing mission is the command signal on class slope, and the control law of altitude channel is:
Wherein, Δ z is height error,It is short transverse speed,It is short transverse acceleration, Δ δcFor altitude channel control
Amount processed,Expression pairDerivation,WithIt is control parameter, constitutes PID control rule.Control
The output Δ δ of rulecIt is superimposed upon on motor, so, when unmanned plane is highly less than Desired Height, motor speed can be increased, lift-rising;
When unmanned plane highly exceedes Desired Height, motor speed reduces, and produces a kind of automatic control effect of negative-feedback.These three controls
Parameter processed also debugs out using the scheme of " first according to modelling, adjustment is tested again ".
(3) horizontal direction control law
Position control is unmanned plane TRAJECTORY CONTROL.TRAJECTORY CONTROL mainly by it is vehicle-mounted guiding subsystem feedback positional information not
The position of unmanned plane is corrected disconnectedly to ensure landing point that unmanned plane is dropped on vehicle exactly.As shown in Figure 4, pitch channel
Rate information is fed back to by position deviation and P controls by inner looping by PID control respectively with roll channel.
Many horizontal x directions Landing Controls of rotor unmanned helicopter are to be restrained with the tracing control in horizontal x directions as external loop, with
Angle of pitch control rate is inner looping;Wherein, the tracing control rule in horizontal x directions is:
Many horizontal y directions Landing Controls of rotor unmanned helicopter are to be restrained with the tracing control in horizontal y directions as external loop, with
Roll angle control rate is inner looping;Wherein, the tracing control rule in horizontal y directions is:
Wherein, Δ δθ、ΔδφRespectively x, y direction controlling amount,The respectively speed data in x, y direction, Δ x, Δ
X ' is site error and the error change rule in x-axis direction, and Δ y, Δ y ' are the site error and error change rule in y-axis direction,WithIt is the control parameter in x-axis direction,WithIt is the control parameter in y-axis direction,
Δ x is equal to the difference of the positional information x and 0 under many rotor unmanned helicopter rectangular coordinate system N, and Δ y is equal to many rotors, and nobody is straight
The difference of the positional information y and 0 under machine rectangular coordinate system N is risen, e is a fixed error value, and the value is determined by actual conditions,
Generally 10cm.
So that unmanned plane is in the tracing control rule in horizontal x directions as an example,WithConstitute PID control rule.
The output Δ δ of control lawθIt is used as the input of pitch channel inner looping.So, when unmanned plane is located at vehicle landing point rear, the phase
The angle of pitch of prestige is, on the occasion of increase, to act on inner looping and increase unmanned plane forward flight speed;Conversely, when unmanned plane lands positioned at vehicle
During point front, the desired angle of pitch increases for negative value, acts on inner looping and reduces unmanned plane forward flight speed.This four control parameters
Also debug out using the scheme of " first according to modelling, adjustment is tested again ".It is demonstrated experimentally that this control program is simply easy
OK, effect is notable.
Each loop is all that, using classical pid control algorithm, need to choose rational control parameter from inside to outside above, is made each
The command signal of individual channels track controller, improves its stability.The selection process of parameter is that elder generation is according to modelling by mechanism and distinguishes
The result for knowing modeling picks out each channel transfer function, for the method successively design control law of single channel root locus;It will set
