It is the estimated value of X, KFIt is filtering gain.
Step 10: by formula (22) according to the theory of optimal control, pilot optimal operation amount is obtained.
Step 11: the man-machine loop's kinetic model building for observing threshold property with pilot finishes.
Step 2: determining that LSO and pilot arrange manipulation principle.
The thrust of LSO and pilot's agreement is determined according to airplane throttle characteristic and throttle lever setting.Assuming that carrier-borne aircraft is normal
Throttle lever limit when manipulating of gliding is trim position ± 10 °.Then assume the throttle commands corresponding relationship of LSO and pilot's agreement
Such as the following table 1:
Table 1 forces thrust command to arrange table
Wherein δT0It is downslide trim condition throttle lever position.
Step 3: the condition premised on agreement manipulates principle, optimizing is solved and is counted using flight safety index as objective function
Calculate instruction envelope curve.
To guarantee safety of going around, stern headroom is generally required to be at least 3m, therefore flight safety index of the present invention is with stern
Quiet high 3m is standard.In warship commander, LSO prejudges state of flight, if LSO anticipation aircraft reaches stern Shi Jinggao
Then think dangerous less than 3 meters, then LSO assigns corresponding imperative instruction.Herein, the method for computations envelope curve is, to fly
Machine and the deflection ratio deviation delta h at ideal relative position X, the position X of warship pointdotWith height tolerance Δ h0For independent variable, to arrive
The quiet high 3m of bottom stern is objective function, is input with a certain imperative instruction, using conjugation using first step MOCM-AEW model
Gradient method optimizing, then the corresponding deflection ratio deviation of available one group of imperative instruction and height tolerance curve set, that is, refer to
Enable envelope curve.
Step 4: summarizing imperative instruction envelope curve, forms LSO and instruct production system.
" to a throttle, recovery thrust, open out, opening reinforcing ", four curves summarize, that is, form LSO pressure and refer to
Enable production system.
Embodiment 1:
Below with " giving point throttle " instruction instruction envelope curve calculating process and beneficial effect of the present invention.
Step 1: establishing the man-machine loop's kinetic model (MOCM-AEW) for observing threshold property with pilot.Wherein
Model parameter is as shown in table 2.
2 MOCM-AEW model parameter of table
Step 2: it is as shown in table 1 to determine that LSO and pilot arrange manipulation principle.
Step 3: the condition premised on agreement manipulates principle, optimizing is solved and is counted using flight safety index as objective function
Calculate instruction envelope curve.According to the previous flying experience of LSO, " giving a point throttle " be occurred according to the bias state and deviation of aircraft opportunity to
Out.Analogue simulation is carried out to LSO flying experience using MOCM-AEW pilot model thus.Calculated result is as shown in Fig. 2, root
According to initial deflection ratio deviation delta hdot, distance it is ideal warship point distance X, height tolerance Δ h0, give the LSO " to a throttle " and refer to
Enabling allows area.As shown in Fig. 2, dash area is to instruct to allow area under every curve.Simultaneously as calculating the target letter used
Number is quiet height at stern, thus instruct allow area location boundary be x=-80m, i.e., stern point relative ideal warship point coordinate.
By emulation as it can be seen that with deflection ratio increase, instruction allow area be gradually reduced.As aircraft is close to stern, LSO instruction allows
Height tolerance is gradually reduced.This is consistent with actual conditions.To illustrate that instruction allows the reasonability in area, it is respectively compared instruction packet
Inside and outside line it is each a bit, such as A point in Fig. 2 and B point, example deflection ratio increment is 4m/s, and deviation appearance position is X=-300m, height
Deviation is respectively Δ hA=-15m and Δ hB=10m.Carry out warship emulation, A point, B point and ideal warship warship track such as Fig. 3
Shown, the quiet height of A point and B point at stern is -4.7423m and 14.8617m (being positive downwards) respectively.Obviously it flies for B point
State, even if LSO gives " giving point throttle " instruction, aircraft will hit warship.Therefore can be illustrated by the calculating of this instruction,
LSO instruction envelope curve calculating of the present invention is accurate and reasonable.
Step 4: summarizing imperative instruction envelope curve, forms LSO and instructs production system.It is same to calculate " restoring thrust ", " add
Throttle ", " opening reinforcing " instruction envelope curve as shown in figures 4-6.With Δ hdotMore identical deflection ratio different instruction for=2m/s
Instruction envelope curve, as shown in Figure 7.Referring to Fig. 7, wherein region 1,2,3,4 is deflection ratio Δ hdotWhen=2m/s " to point a throttle ",
The instruction area LSO of " restoring thrust ", " open out " and " opening reinforcing ".And aircraft bias state once enters region 5, even if flight
Member opens reinforcing, and aircraft, which reaches the quiet height of stern, will be less than 3m, generation it is larger warship risk.
LSO after summarizing forces the application method of thrust command as follows:
Step 1: carrying out state judgement to each moment (position X) into after decision point of going around.According to position and currently
Deflection ratio (X, Δ hdot), progress two-dimensional interpolation, calculating current state is corresponding " to a point throttle, recovery thrust, open out, to be added
Power " envelope curve height tolerance boundary value.
Step 2: according to current flight state (X, Δ h, Δ hdot), according to instruction envelope curve, select LSO instruction.
Step 3: being instructed according to LSO, pilot is manipulated or carries out more human-computer interaction closed-loop simulations according to instruction.
It is thus achieved that LSO forces thrust command modeling and simulation.
Embodiment 2
Warship emulation is used to verify LSO demand model below.If under LSO commander, the landing precision of aircraft
It is improved with safety, then just illustrating that LSO modeling provided in the present invention is reasonable.Simulating, verifying example parameter such as table
Shown in 2.For the drift correction ability under clear relatively LSO instruction, the influence for avoiding randomness from generating is removed in warship emulation
Atmospheric perturbation influence.It is forced in class thrust command simulation in LSO, sets differential location X=-1429m, initial deviation Δ hdot
=4.5m/s, Δ h=20m.Comparing LSO forces the flight simulation result under thrust command as shown in figure 8, for intuitive display, only
Give end orbit enlarged drawing.Fig. 9 is that figure is compared in the pilot guidance under LSO commander.As seen from Figure 8, it is commanded without LSO
When, quiet high h=-1.0543m (inverted triangle track) of the aircraft at stern, (the circle when only LSO info class and suggestion class instruct
The locus of points), quiet high h=-1.7147, and LSO is assigned after forcing thrust command, quiet a height of h=-3.9491m (the positive triangle rail of aircraft
Mark).Ensuring the reasonability in flight safety by this comparative descriptions LSO imperative instruction.Fig. 9 shows LSO and refers to simultaneously
Pilot guidance behavior under waving, it is seen that when away from warship 480m or so, LSO, which has been assigned, opens reinforcing instruction, thus ensures winged
Machine flight safety.
The present invention can not really instruct with LSO for tradition LSO and establish associated status.Thrust command is forced to be adopted LSO
It is obtained with virtual flight experience, establishes LSO imperative instruction envelope curve, form LSO instruction production system.Embodiment shows LSO
Commander is improving landing precision, it is ensured that plays a significant role in terms of flight safety, this illustrates LSO demand model modeling of the present invention
The reasonability and model accuracy of method.
