The repeating coil and transmitting coil are each attached to track girder bottom, and the turn ratio of transmitting coil and repeating coil is 5:3。
A kind of suspension type monorail traffic track beam routing inspection trolley control method, comprises the following steps:
Step 1, establish lagrangian dynamics model:By routing inspection trolley motion when horizontal displacement, vertical displacement and Speed establishes Lagrange's equation, and thus obtains the total kinetic energy of routing inspection trolley.Lagrange's equation is:
In formula, L be system of material points kinetic energy and potential energy difference, qjFor the generalized coordinates of the system of material points, j is number of degrees of freedom, FjFor Generalized force.
According to Lagrange's equation, the horizontal displacement x of routing inspection trolley is listedmWith vertical displacement ymFor:
The kinetics equation of the system is:
In formula, x is the displacement that routing inspection trolley connects guide rail operation, and m is routing inspection trolley quality, and l is to connect rail length, θ For pivot angle, g is acceleration of gravity.
Step 2, nonlinear equation linearisation:Routing inspection trolley model in step 1 is subjected to linearisation abbreviation, and determined The governing equation of routing inspection trolley.
Because connection rail length l is constant, and when pivot angle θ very littles, cos θ=1, sin θ=0, by dynamics side It can be obtained after Cheng Huajian:
Step 3, establish fuzzy control model:The governing equation of routing inspection trolley in step 2, establishes fuzzy control Model, input quantity is determined into a fuzzy subset, a Triangleshape grade of membership function is established, degree of membership is entered with the mode of extreme difference Row statement, driving force, pivot angle, the membership function of go up a slope shake and bend inspection are stated out respectively, and determine Fuzzy Control molding The input variable and output variable of type.
Step 4, Xie Mo are solved:Carry out fuzzy reasoning by the fuzzy control program in step 3 and solve mould to solve.
Carry out vague description to membership function with fuzzy condition statement, the control rule of fuzzy controller be by one group that The dimmed conditional statement that is connected by the annexation of "or" around here describes, each of which fuzzy condition statement, When input, output language variable reacted on respective domain the fuzzy subset of each Linguistic Value for it is known when, can be expressed as discussing Fuzzy relation on the collection of domain.Fuzzy controller receives Indistinct Input amount, by fuzzy logic inference, finally gives controlled data volume Fuzzy control quantity.Because fuzzy control quantity cannot be directly used to the control of controlled device, the control variable of controlled device is necessary For precise control amount, so, de-fuzzy is carried out to membership function using gravity model appoach, takes some points that represent to be used as degree of membership letter Several relevant variable parameters.
Lagrangian model described in step 1 is modeled using vector dynamic behavior.
The foundation rule that fuzzy control model is established described in step 3 is to tremble the driving force of routing inspection trolley, pivot angle, upward slope The dynamic variable with bend inspection is subject to abstract generalization, summarizes and emulates its validity, and then draws corresponding fuzzy language set.
It is described to represent the point a little surrounded as membership function curve and axis of abscissas in the center of gravity of area.
The present invention compared with prior art, has the advantages that, of the invention is rational in infrastructure, passes through wireless charging skill Art carries out wireless charging to routing inspection trolley control device, the inspection distance of routing inspection trolley is increased, using fuzzy control and glug Bright day model is combined, and increases the control accuracy of routing inspection trolley.Automaticity of the present invention is high, system run all right and can High by property, control accuracy is high, service life length.
