Fig. 3 is the interior PID control structure of speed control unit of expression frequency converter 21.Fig. 3 has increased pulse/frequency inverted portion 53 and PID result of calculation correction portion 54 on the frequency converter of Fig. 1.In addition, because frequency converter 22 is also identical with frequency converter 21, its explanation of Therefore, omited.
Guiding bobbin 3 has when batching bobbin 2 and batch sliver S1～S5, rotate and guide the function of sliver S1～S5 corresponding to the rotation of batching bobbin 2, owing to itself do not batch the action of sliver S1～S5, do not rise so do not produce the linear velocity that causes because of the expansion (batching increase) of batching sliver.At this moment, in the present embodiment, utilize speed sensor 10 to detect the rotative speed of guiding bobbins 3, utilize frequency converter 21 to keep its rotative speeds to control the rotative speed that batches bobbin 2 regularly, keep with this and batched the linear velocity that bobbin 2 batches sliver and fix.
In order to carry out the controlled reset by the electrical motor 11 of this speed sensor 10, frequency converter 21 has the speed controlling portion of control motor 11 rotative speeds (batching the rotative speed of bobbin 2) as shown in Figure 3.
Speed controlling portion has: input is corresponding to the frequency instruction FR[Hz of the linear velocity instruction that comes self-controller 42] acceleration and deceleration portion 50; Input is corresponding to the frequency detecting value Fb[Hz from the linear velocity detected value of pulse/frequency inverted portion 53] and corresponding to frequency instruction value Fin[Hz from the linear velocity command value of acceleration and deceleration portion 50] subtracting section 51 and with the outgoing side bonded assembly PID calculating part 52 of subtracting section 51.
Acceleration and deceleration portion 50 sets the frequency instruction FR[Hz that supplies with from control part 42] the acceleration and deceleration time constant.So-called pick-up time constant is meant that the electrical motor 11 of halted state reaches the time according to maximum frequency that V (voltage)/F (frequency) fixed control is set (for example 300[Hz]), and so-called deceleration time, constant was meant that electrical motor 11 is from maximum frequency 300[Hz] operative condition reach time of halted state.
Subtracting section 51 deducts frequency detecting value Fb from the frequency instruction value Fin of the acceleration and deceleration time constant that acceleration and deceleration portion 50 sets, and obtains its deviation delta F.
It always is that 0 ground carries out PID calculating that PID calculating part 52 makes deviation delta F, has: ratio calculating part, integral and calculating portion, differential calculation portion and the portion that adds.

Pulse/frequency inverted portion 53 after detected pulses outputs [rad/s] are converted to revolution [rpm] with speed sensor 10, gain as shown in Figure 4 adjustment (* G), to be scaled frequency number [Hz] by the revolution that gain is adjusted, and as frequency detecting value Fb (for example, Fb=300[Hz]) to subtracting section 51 outputs.
In the present embodiment, except the PID control structure of frequency converter shown in Figure 1, appended output with respect to PID result of calculation, carry out two kinds of controls, promptly (1) utilize output frequency to revise the calculating of the output of PID result of calculation, (2) add the limit on this result of calculation structure.
To begin be exactly high speed to the electrical motor rotative speed of general high-speed wind-up device batching, with the time of batching becomes low speed gradually.Therefore, the output frequency of frequency converter also is controlled as low frequency gradually.That is, the output frequency of frequency converter is more little, and PID result of calculation is big more to the variation reflection of the output frequency of frequency converter.At this moment, in the present embodiment, in frequency converter 21, possesses the PID result of calculation correction portion (correction mechanism) 54 that the output frequency that is used for frequency converter is more little, PID result of calculation is also carried out Correction and Control with diminishing.
PID result of calculation correction portion 54 has: the last secondary frequencies input part 60 of the output frequency Fout (n-1) of one-period in the input (output frequency that last time, frequency converter 21 was exported to electrical motor 11); PID result of calculation from this cycle that the PID calculating part is exported, deduct the output frequency Fout (n-1) from the last one-period of last secondary frequencies input part 60 outputs, obtain the subtracting section 61 of its deviation and successively with outgoing side bonded assembly frequency dependence calculating part 62, the limit portion 63 of subtracting section 61 and the portion 64 that adds.
Below, the calculated examples of utilizing PID result of calculation correction portion 54 is described.
Usually, PID control is carried out repeated calculation with the fixed cycle, with the output frequency of Fout (n-1) as last one-period, with the output frequency of Fout (n) as this cycle, with Fin as frequency instruction value.
Is output frequency from the PID result of calculation (PID output) of PID calculating part 52 output example in the past, but this output frequency is not intactly exported to electrical motor 11 in the present embodiment, but utilize subtracting section 61, calculate the deviation of the output frequency Fout (n-1) of PID output and last one-period according to following formula.
PID computing value deviation=PID output-Fout (n-1) ... (formula 1)
At this moment, when as the PID computing value deviation of the result of calculation of (formula 1) when big, PID output changes sharp, and linear velocity also fluctuates.
Here, be shown below, utilize frequency to rely on calculating part 62 depends on the size of output frequency according to the result of above-mentioned formula 1 calculating.
Frequency relies on computing value=PID computing value deviation * (Fout (n-1)/Fin) ... (formula 2)
The calculating of (formula 2) is equivalent to the ratio with output frequency Fout (n-1) size of frequency instruction value Fin and last one-period, reduces PID computing value deviation.
After the calculating of (formula 2), in order further to suppress the variation sharp of PID output, by by limit portion 63, the limiting frequency according to the predefined resolution of setting resolution of regulation relies on computing value to the frequency of calculating and handles in the positive and negative enforcement limit of this frequency.At this moment, limiting frequency can for example at random be set with cps by the user.In addition, in order to improve extreme accuracy, set resolution and for example be preferably 0.01Hz.
To implement frequency that the limit handles as described above with the portion 64 that adds and rely on final output frequency Fout (n-1) addition with the previous cycle of computing value, with this output frequency Fout (n) of addition result, to electrical motor 11 outputs as this cycle.
Fig. 5 is motor rotative speed-the batch curve of time response of the batch up gear of expression present embodiment experimental result, and Fig. 6 represents in the past the motor rotative speed of example laboratory result's batch up gear-the batch curve of time response.This experimental investigation the linear velocity of batch up gear be the 3200m/ branch, at 60 minutes output frequency Fout with frequency converter 21 from 120[Hz] the variable 30[Hz of controlling to] and the time motor rotative speed-batch time response.According to two experimental results, in example in the past, when the motor rotative speed is big, produce rotary pulse, but can confirm to have suppressed generation in the present embodiment as this rotary pulse on amplitude ground.Therefore, present embodiment can change by limit treatment limits is maximum by the big or small Correction and Control PID result of calculation of output frequency, and its result shows, can suppress the steep variation of PID output (PID result of calculation), make the linear velocity fixed control of stable high-speed spinning batch up gear become possibility.
Therefore, according to present embodiment, on-line velocity fixed control aspect, use the speed sensor of detection line speed etc., this speed detection information is passed to the frequency converter as supply unit that is used for driving motor, make this linear velocity detected value and linear velocity command value carry out PID linear velocity fixed control much at one in frequency converter inside, in this structure, because PID result of calculation to the electrical motor rotative speed when high and the result of calculation when low change, reach low speed more, reduce PID result of calculation ground more and revise, so can stablize the high-speed wind-up state.In addition, owing to can limit of utilization mechanism limit, so that do not export PID result of calculation not superfluously, so can further stablize the high-speed wind-up state.Promptly, according to the present invention,, thereby can suppress the steep variation of PID result of calculation by big or small Correction and Control PID result of calculation to the output frequency of electrical motor output, can satisfy the requirement of control accuracy, become possibility with the linear velocity fixed control of this more stable batch up gear.In addition, in the present invention, also the limit of utilization treatment limits maximum variation, thereby further improve linear velocity stability, can further stablize the state that batches.Like this, utilize present embodiment, can be with easy adjustment and the low cost system structure that need not append peripheral equipment etc., make the high precision linear velocity fixed control of realizing the high-speed spinning device become possibility.
In addition, the present invention is not limited to the above embodiments, in the scope under the present invention, can all distortion implement the foregoing description.
