Formula (6), (7) shown that the speed between the adjacent twice of interlocking equipment time exists certain ratio relation, and formula (8), (9) then shown when external condition (such as compressibility) when changing, this ratio relation is no longer constant, speed or velocity setting amount that speed of preceding a time or velocity setting amount can be expressed as back a time multiply by scale-up factor and corresponding departure sum, this just gives a kind of enlightenment of design of Controller, with the N passage is example, the N passage is last passage, its roller/tube speed has determined the speed of production of finished-product material, therefore the motor rotational speed of this a time is often directly given by operator's console, the motor rotation of N-1 passage be multiply by the departure that scale-up factor adds the N-1 passage by the motor rotational speed of N passage, and the rest may be inferred for other.
As can be seen from Figure 1, between two adjacent roller/tubes, exist the tuner of an activity, the purpose of placing tuner is exactly in order to coordinate two rollers/tube speed, at each tuner place position or tension pick-up are housed all, be used for detecting the position or the tension force of tuner, in general, when metal material does not have tensioning, tuner relies on the counter-force of self outwards move (the downward direction of arrow among Fig. 1), when the metal material tensioning, tuner is then pulled to interior motion (the upwards direction of arrow among Fig. 1) by metal material.In the range of movement of tuner has and the outermost limit, the centre position of general tuner is the optimum position of metal material work, equally will be the target location of centre position as control during electrical control.With roller/tube N, roller/tube N-1, tuner N-1 three's pass is example, during operation, when tuner N-1 position partially outside the time, illustrate that the travelling speed of roller/tube N-1 is faster than roller/tube N, by control algolithm, reduce the speed of roller/tube N-1; Otherwise, when tuner N-1 position partially in the time, illustrate that the travelling speed of roller/tube N-1 is slower than roller/tube N, by control algolithm, improve the speed of roller/tube N-1.Like this, can remain tuner N-1 in the centre position.Equally, be example with roller/tube 3, roller/tube 4, tuner 3 threes' pass, when tuner 3 positions partially outside the time, illustrate that the travelling speed of roller/tube 3 is faster than roller/tube 4, by control algolithm, reduce the speed of roller/tube 3; Otherwise, when tuner 3 positions partially in the time, illustrate that the travelling speed of roller/tube 3 is slower than roller/tube 4, by control algolithm, improve the speed of roller/tube 3.Like this, can remain tuner 3 in the centre position.The speed of other roller/tube and the relation between the tuner are analogized.
From top analysis as can be seen, in order to make the motor speed n of i-1 passage
I-1Follow the tracks of the motor speed of i passage fully, adopted the control mode of feedforward+adjusting, the control algolithm of regulator is advanced control+PID, and wherein feedforward amount is the motor speed n of preceding a time
i(or G

I-1, regulated quantity is Δ n
I-1(or Δ G
I-1), just formula (8), (9) represented situation.This scheme is the most practical, and precision is the highest, response is the fastest.
The speed of winder is the speed of following finished product roller/tube N, the working condition of its working condition and roller/tube is different, when metal material is not strained, tuner relies on the counter-force of self outwards move (the downward direction of arrow among Fig. 1), the operating rate that winder is described is too slow, and should improve the operating rate of winder this moment; Otherwise when metal material was strained, tuner was then pulled to interior motion (the upwards direction of arrow among Fig. 1) by metal material, illustrates that the operating rate of winder is too fast, and should reduce the operating rate of winder this moment.In addition, the coil diameter of metal material is increasing on the rolling wheel in the course of the work, and variation has taken place the rolling radius, then the speed n of winder motor

If the various work relationships of interlocking equipment can be by operating personnel's the confirmable words of experience, other relates to the design that profound technical matters then needs the technician so; Relating to theoretical question then needs the support of mathematics.In the technical indicator of interlocking equipment, the time that stops, stopping soon for metal material when stopping fast not disconnecting, just requires the speed of each roller/tube to keep strict rapport generally much smaller than starting crawl time, in formula (8), (9), and Δ n
iWith Δ G
iOutput by regulator (controller) produces, and in quick stopped process, same requirement can produce rational Δ G fast
i(Δ n
i), in the PID control method, rapidity and stability are contradiction, during design, generally at first guarantee stability, solve rapidity then.Solving the method for following the tracks of fast has two: one, by advanced control theory, detect the position of tuner, set extreme position, when the position of tuner during in the inside of board and near extreme position, the velocity setting voltage of a time frequency converter before then improving fast, before improving fast the travelling speed of the speed of a time motor and roller/tube with quick tracking after the speed of a time roller/tube; When the position of tuner during in the outside of board and near extreme position, the velocity setting voltage of a time frequency converter before then reducing fast, the travelling speed of the speed of reduction motor and roller/tube is (to annotate: mechanically said back a time with the speed coordination of back a time roller/tube fast, the preceding a time that in control should be, for unification, all be as the criterion) with saying mechanically.The 2nd, by the Parameter Self-learning method, calculate actual velocity ratio K
Is, make regulated quantity Δ n
iWith Δ G
iBe tending towards 0, realized quick response.
The single pass control often of interlocking equipment control algolithm in the past, entire combination, be that the movement velocity of each passage causes after according to preceding a time mechanism kinematic back a time mechanism position sensor to change carrying out PID after the feedback regulating, this method can't satisfy interlocking equipment both had very high requirement to control stiffness, again the control rapidity was had strict index request.From controlling the control stiffness that angle at first will guarantee equipment, its rapidity realizes by asynchronous self-learning algorithm.For the feasibility of the method is described, at first suppose the ratio of the adjacent two passage length velocity relations of known interlocking equipment, the datum velocity of back a time mechanism is that the speed of preceding a time multiply by this ratio so, the actual speed of back a time mechanism is exactly the regulating and controlling amount that datum velocity adds position sensor feedback, because the regulating and controlling amount has been the effect of a fine setting, and determined the stability of equipment, so the parameter tuning of controller can mainly be considered stability.And the rapidity of equipment is decided by the ratio of adjacent two passage length velocity relations.
Though the initial value of this ratio can or calculate by field adjustable and obtain, the ratio relation of adjacent two passage length velocity relations changes in real system, thereby has adopted ASYNCHRONOUS LEARNING CONTROL SYSTEM in controller.Control system can constantly be adjusted this parameter in the process of operation, make them approach optimum value step by step, thereby the performance of the system of improvement is to improve the output and the quality of product.The learning algorithm of interlocking equipment electric control system is as follows: the 1. preceding setting according to operating personnel of operation, the velocity ratio K that presets from database between corresponding each the roller/tube of acquisition and certain kind metal material
iWhen 2. moving, from frequency converter, read the speed of each motor.3. calculate actual each roller/tube velocity ratio K respectively
i4. according to the velocity ratio K that learns gained
IsAnd the velocity ratio K that presets that sets
i, make the velocity ratio K that presets
iGradually to the velocity ratio K of reality
IsApproach, on this value basis to the regulator operate as normal of each roller/tube speed.5. the velocity ratio that will learn gained deposits mnemon in.Reached the perfect unity of rapidity and stability by self study.
