The drawing shows a block diagram of optjMHcsaTOpa.

The device comprises a pulse driver 1, an increment unit 2, a clock generator 3, a pulse generator 4, counters 5, 6, 7, assembly circuits 8, 9, 10, coincidence circuits 11-16, comparison circuits 17, 18, delay circuits 19, 20, triggers 21-26, and an additional device 27, a control object 28, and a button 29.

The optimizer works as follows.

When the button 29 is pushed by immersions of the generator 4, the shaper 1 is triggered, the output of the Hoii signal of which sets to the state "On triggers and Counters 5 and 6, and in the meter 7 it sets" 1. In the initial state, one of the inputs of the coincidence circuit 11 receives the resolving potential from the zero output of trigger 24, and the coincidence circuits 12, 13, and 16 are closed, since one of the inputs of each circuit is connected with the first output of one of the triggers.

The function at the output of the object varies by law and (t) U (t). In momeite times O, IT, 2T ...., pT, determined by the pulses of clock geierator 3, period 7, block 2 generates pulses at the output

+ D, if D "(pT) and (pT - T) - 0; - D, if D „- and (pT) - and (pT - T 0.

The pulses -f-D and -D come on g move1; I and 12 match circuits, and the output of assembly circuit 9 either is either an impulse or not, i.e. CP = 0, or (. The signal from the output of circuit 9 connects to the input of the actuator 27, the algorithm of which and:, 1eet

Devices on the i-th cycle: lo iT: f / o, i.e., constant level of the search of an arbitrary sign. The output signal from the external device 27 is connected to the object 28.

where m is the automatically selected upper limit of the number of blocked pulses in the stationary mode.

Suppose that the system began to move

to extremum. In this case, block 2 gives impulses - {- L. Under the action, -. pulses - L flip-flops 2i, 22 switch to the state.% flip-flop 23 also translates to the state v / l / differential voltage from a unit voltage.

trigger 22. From the single output of the trigger 21, the resolving level of the search engine is supplied to the coincidence input 12. Due to the fact that the object has a parabolic characteristic, after several cycles the output pulses of block 2 will become negative through the coincidence output 12 will pass to the 15th run of the counter 5, and the trigger 22 is transferred to the state “O, the riggers 23 and 24 will not change their states. At the same time, negative pulses of -D pass through coincidence circuits 11 and 9 and 9 each switch the actuator 27. All / e of the pulses from the output of circuit 9 fall on the input:) The additional device, and the number / g is set in the counter 5 .

Then the emiles from the output of block 2. Change the sign. The first of these imicules is iicpei; it triggers triggers 21 and 22 J3, which is “1”. By the voltage drop from the unipital ihlipa ipni-gera 22, the flip-flop 23 switches i; the state H11i and “O, and the trigger 24 is transferred to the state“ 1 voltage transfer from zero, 1a trigger 23. The circuits coinciding H 11 and VI receive the inhibitory potential at the input; -., ci i with zero output of trigger 24, and the coincidence circuit 13 receives the resolving potential "and the input connected to the unit one: the output of the trigger 24. At the next batch of negative impulses, the output of the block 2 of the coincidence squad 13 triggered, and from its output a. P) they carry the circuit 1) / kk 19 to the input Counting 6, a. through the scheme coincidence b) - pa V. vgood of the counter 7. The first l | 1M11 L1 of the common output of the coincidence circuit 13 passes

sovnadein scheme) 14, since its input is connected to the output of the counter 6. From the output of the eojsnadenn 14 scheme, the first impulse of the pack —L passes through exem 9 to the input of the splicing device and, in addition, switches the trigger 25

to the state "1, and from the output of the delay circuit 19 writes down" 1 in the counter 6, as a result of which the circuit 14 of the charge 14 is closed. Next, then the pulse of the packet -D passes only; ja the inputs of counters 1 and 6 and 7. The good news is that

the non-switching of the penitentiary system, as a result of which the system was rotated to move to the extremum, was carried out with a flat impulse - D, and the remaining impulses are blocked. The system returns to the ecetremum in m cycles. The number T is stored in counter 6, and the number (m-f-l) is counted1; ike 7.

If the system happens randomly, or there is no shutdown,

Exit 1, to an extreme can require cycles. The achievement of the case is revealed by the comparison circuit 17. In the case of m - k, the pulse arriving at the comparison circuit 17 through the delay circuit 20 passes to the assembly circuit 10 and starts the shaper 1. When the shaper is triggered once, all triggers and counters are set to the initial state. The delay circuit 20 provides this setup at a time that does not coincide with one of the moments pT, and if, after comparing mk, the bundle -L did not run out, the remaining pulses go to the input of the actuator through the coincidence circuit 11. Then, from the output of unit 2, a packet of positive pulses + A, and the following pulses -A will all pass to the actuator, and counter 5 will remember the number of pulses -A. In the next cycle, the actuator switches only with the first impulse from the negative-A-batch of pulses, the remaining impulses and, consequently, the switchings are blocked. If at the same time the case is achieved, the scheme is compared; 17 does not provide a signal for triggering and CM.iiiiKOB to the initial state. With the end of the negative pulse bursts -A, the counter 6 is in the state w, and the counter is in the state (t - | -1). The first impulse G1O is v1; it then packs + A through the assembly circuit 8 and translates counter 6 into the zero state. At the same time, the pulses of the bundle +, the passage of the coincidence circuit 16, set the trigger 26 to the state "1, and the coincidence circuit 15 closes until the next operation of the forwarder 1. Up to this point, the counter 7 will store the number (t + 1). The blocking control will continue until the current number of pulses in the -A packet becomes (as a result of accidental failure or change of the system parameters. In this case, the circuit 18 gives out (t + nth imiulus inchkn - L to the input of the imager 1 In this case, the triggers and counters are transferred to the initial state, go through the control cycle without blocking, and then all switches of the spouting device, except the packet corresponding to the first pulse -A at the output of block 2, are blocked again. At the same time, a new The pn boundary t will continue to adjust with blocking the new number of pulses. Thus, delay circuit 20, counter G and coincidence circuit 14 allow ocyHiecTvit blocking a burst of pulses -A, except for the first one, which leads to a faster removal of the object to the extremum and tracking error Counter 7, which records the minimum number of ticks required for the tracking process with blocking of unnecessary non-switches, with the comparison circuit 18, allows speeding up in case of a crash or change of the parameters of c1b: the output to the extremum, i.e. ehoustoychivost system.
