Description
Известен способ экстремального регулировани с наложением модулирующих колебаний и непрерывныл медленным смещением уставки. В случае интенсивных помех этот способ не может дать хорощих результатов .There is a method of extreme regulation with the imposition of modulating oscillations and a continuous slow offset of the setpoint. In the case of intense interference, this method cannot give good results.
Дл выделени полезного сигнала путем определени знака (и скорости ) перемещени уставки предлагаетс способ, по которому производитс возвратно-поступательное смещение уставки; этот процесс ловгор етс столько раз, сколько требуетс дл определени полезного сигп;;1 ,ia с необходимой точностью (чем выще урогзень помех, тем больще число повторений). Смещение уставки в сторону экстремума производитс после заверщени необходимого этапа из п циклов колебаний уставки. П(;с,;1е этого процесс колебательного смещени уставки повтор етс .To isolate the useful signal by determining the sign (and speed) of the setpoint movement, a method is proposed that is used to reciprocate the setpoint; this process is logged as many times as is required to determine the useful sigp ;; 1, ia with the necessary accuracy (the more noise, the greater the number of repetitions). The setpoint is shifted towards the extremum after the necessary stage is completed from n cycles of oscillation of the setpoint. P (; s,; 1e) the process of oscillating bias of the setpoint is repeated.
Могут представитьс случаи, когда в помехах подчеркнуты составл ющие с некоторыми определенными частотами. Дл уменьшени опасности совпадени одной из этих частот с частотой модулирующих колебаний целесообразно иметь частоту модулирующих колебаний в каждол атапе из п циклов переменной. При этом совпадение (близость) частот будет наблюдатьс лищь в течение короткого промежутка времени.There may be instances when components with certain frequencies are underlined in interference. In order to reduce the danger of coincidence of one of these frequencies with the frequency of modulating oscillations, it is advisable to have a frequency of modulating oscillations in each step of n cycles of a variable. At the same time coincidence (proximity) of frequencies will be observed only for a short period of time.
Указанный способ оказываетс полезны.м также в тех случа х, когда система регулировани имеет собственные частоты и по вл етс опасность попадани модулирующих колебаний в резонанс с нилш.This method is also useful in cases where the control system has its own frequencies and there is a risk that modulating oscillations will fall into resonance with the cylinder.
При необходимости вести экстремальное регулирование по нескольким параметрам одновременно, можно использовать один и тот же iiiiтервал частот модулирующих колеба{н-1Й, дела различными дл различных параметров законы изменени частоты в каждом этапе из п циклов . Если /г:-- 2, т. е. происходит смена направлени движени только один раз, указанный способ можно использовать, дела переменными по времени (по заданному закону) частоты модулирующих колебаний.If it is necessary to conduct extreme regulation on several parameters at the same time, one and the same iiii frequency range of modulating the oscillations can be used. The laws of frequency variation at each stage from n cycles are different for different parameters. If / g: - 2, i.e., the direction of movement is changed only once, this method can be used by making the frequency of the modulating oscillations variable in time (according to a given law).
На чертеже представлена прл.лсриа схема выполнени устройства ио описываемому способу.The drawing shows the scheme of the device according to the described method.
