(54) METHOD FOR ADAPTIVE CORRECTION OF TWO-CHANNEL

FOLLOWING SYSTEM The following is typical for the prototype method. 1. Along with the nonstationarity of the Dynamic properties of the system, the essential role of the file; The tracking process plays the stationarity of the extrinsic characteristics of the control object, which is not provided for in the prototype method. Thus, for example, the non-stationarity of 9kst {map1 "A characteristics of the radiation field and self-guidance of the radiation leads to the development of the system); I 2. By virtue of the specificity of the screening method, established by B. rss- “svdedeldeki guidvent of fukotv /: kacheg. gwa, proto-scapula is critical to the volume There with local extremes in the sun by ferro vazmuertnmi mi 3. Based on the algorithm of the method-proto. types of difficult, discrete signals of proportional signals proportional to the cJcop ocT drift of the Extreme Characteristic. 4. For the xapetcreptm prototype method, the limitation in instrumentation is for multidimensional and multi-dimensional optimizer. ;% .. The purpose of the present invention is to develop such a method of adaptive correction, which allows a two-channel tracking system with a controlled frequency of the search signal to be built, aesthetic, and accuracy. Automatic search and search engine sGhGKI i.pi unstable EHTUESHINES AND DYNAMIC CHARACTERISTICS OF HK, AND IMPROVE THE SELECTION OF TARGETS IN THE GROUP OF GOALS (MULTI-EGGS (EXTREME, ME: ZACHA) Expand Functional VoIs, CssBocTR Systems. -.. --- ...-. - iJ;,. -. -. ., „„ -.- .: -. According to Cossack, the posturing goal is comprehended by the fact that control channels of control channels are brought in. About a friend flpyf, differential p - Rot output: a frequency channel, a SyShT signal, a phase shift signal, phase shift, a zero transition, a zero channel, or a zero channel equip- ment, or a zero channel equip- ment. After one eighth of the oscillation period, the signal is received, the output from the tanga is at the angle of the file shift, the resulting 5E "cal is compared with the Differentiated KaHanosV exit points depending on the ratio of signs of these sags. formachekug frequency control signal 8. control signals and control channels., In the drawing, a two channel servo track with an adaptive correction circuit is functionally represented, an illustration one of the POSSIBLE options for the physical implementation of the proposed method. It contains a frequency controlled oscillator 1 of search engine, a phase splitter consisting of frequency dividers 2 and 3, linear links 4, 5, integrating links 6, 7, Model of control object 8, adder 9 and logical blocks 10 and AND "Object 8 The controls and the adder Q form the main parametric connection, and the logical 10 and 1JL, as well as the adder 9, form an adjective corrective correcter. The implementation of the proposed method. .. .. -.-W / ba by the given scheme is that the signal U from the output of generator 1 is fed to frequency dividers 2. 3, At the outputs of frequency dividers 2, Form the signals of the search field U, U5:, shifted by fa) on Kli oTnskItelnodruga friend. In turn, the search controls U-ttUg scan the scanning movements at the output of the integrating links of 6, 7 klkalov These movements allow you to get current information about the state of the control object. Note that one half period of the signal ta of the output generator 1 corresponds to the eighth current period of PONSKO; managements. Therefore, the signals U, U: t, Ja supply the Scuy inputs of the logic blocks 10 a 11 in each case with the output signals. The 1st link is 4 and B. The task of adaptive correction is to control the frequency of the search signals so that the current phase shift v introduced by the uravleiin channels is equal to 4 k1t} 2 ± 1tIk о, 1--. Occ efraocTbSo of this method is given by the fact that bobbing the frequency of Coblande in cacTeiwie is possible both with the frequency of geyrats (parametric source) and the control of the search-signal amphitheater (Signal Booster), In this connection for control. Neither the frequency and / or amplitude use the sign of the deviation of the current phase shift from the value of M sHlC.lii (IcsOH-) of the formation of that sign, consider the time points associated with the signal switching Y and the distance from the time switch of the search control U, U2 and one eighth of their period. If we consider the first switching moment as the start of the h-metric, then the considered moments of time correspond to the phase of search controls equal to i iVlC | 2.i1t | 4Cl O, 1.-L If the extremes of the output codes corresponding to zero coincide with the switching times .U, consisting of one eighth of the current control period from the moments of their switching, then the faiZo shift introduced by the control channels is equal to the optimal one. In this case, the output signal of the logic unit is zero, IF the extremes of the output coordinates do not coincide with the switching times of the signal U. There is a zero-to-one eighth period of the search signal from its switching times, those derivatives of the output coordinates are zero at these times. There are the following combinations of signs of the tangent of the phase angle, the output coordinates, and the search controls: - the output of the signs of the search control signal and the tangent of the phase angle C1 и of the digits coincides with the sign of the p0 | pvodny output coordinate; -the characters of the search control {1U1 of the signal and the tangent of the phase shift angle do not coincide with the sign of the derivative of the output coordinate. In the first case, the frequency of search administrations is small, and the current one is lazy. the shift introduced by the channels is less than optimal. In the second case, the place is inversely dependent. the bridge Thus, a correction signal is generated to increase the frequency, if the input of the signs of control in the tangent of the phase angle coincides with the sign of the output signal of the Correction Board in the MFG corrective unit at the frequency of the code, which is set by the reference unit, which is applied to the unit, the unit will apply the unit, and the unit will apply the signs, it will be applied to the unit, the unit will apply the unit, and the unit will apply the signs, it will be applied, the unit will apply the unit, and the unit will apply the signs, which will be applied to the same frequency, if the pattern is applied, then the unit will apply the unit for the frequency, if it is applied, it will be applied to the unit, and then the unit will apply the signs, it will be applied, if the patterns are applied, then the patterns will be applied to the unit, and the unit will apply the signs, and the unit will be using the same code for the frequency of the unit. does not match with the sign about the input output cosfdiata. If the prv of funkivrova nv divamicheskoy karupervstvkvk replace, then. A corresponding rate is formed at the frequency of the search-management until the optimal phase shift is established in the channels. As a result, the effect of unstable 7.8.6 can be compensated, the non-stationarity manifests itself through the parameters of the extremal characteristic, and its compensation is achieved by a combination of parametric and signal control through the correction channel. Thus, for example, when the level changes, the strain of the days of the extreme characteristic is obtained which is cobctly given by the measuring signal 4 to the amplitude of the search controls in order to improve speed in reducing the extremum search errors. In this case: extreme extremes. the nature of stnkk causes uvlvvchenio (decrease) the frequency of search management. Tait as an optimal condition is violated, the aaapt (correction. Contour is activated). static in dvnamncheskuyu point of ska extremum. In its own cohort, the joint control of the frequency and frequency of the gunmen of the svgnaf, as a combination of a pair of satellite fires, is Synchronous interference control measures in 3 optics About the optics A method of adaptive correction of a two-channel tracking system by adjusting the phase shift between control signals of the system control channels, that, in order to increase the speed & in the accuracy of the method, the control signals of the control channels shift relative to each other differentiate the output signals of the channels, form a signal relay from the tangent of the phase shift angle, fwco the moment of transition signals, after one eighth of the oscillation period, multiply by,. relay tasrtt depended on the tangent of the phase shift angle, compare the received signal; with differentiated output signals of the channels, according to the ratio of the signs of these signals, the frequency control signal of the control signals in the control channels is formed.
