Методы настройки регулятора скорости приводного преобразователя

Abstract

Выполнено исследования блока задания скорости, а именно Ñ„Ð¸ÐºÑÐ¸Ñ€Ð¾Ð²Ð°Ð½Ð½Ñ‹Ñ ÑƒÑÑ‚Ð°Ð²Ð¾Ðº (униполярная и биполярная), линейное изменение сигнала (мотор - потенциометр). Была изучена диаграмма скорости при сглаживании, «быстром стопе». Исследовали ПИ - регулятор на Ñ€Ð°Ð·Ð»Ð¸Ñ‡Ð½Ñ‹Ñ Ð¿Ð¾ÑÑ‚Ð¾ÑÐ½Ð½Ñ‹Ñ Ð²Ñ€ÐµÐ¼ÐµÐ½Ð¸ и ÐºÐ¾ÑÑ„Ñ„Ð¸Ñ†Ð¸ÐµÐ½Ñ‚Ð°Ñ ÑƒÑÐ¸Ð»ÐµÐ½Ð¸Ñ, пришли к оптимальному варианту. Полученный вариант отстает от Ð²Ñ Ð¾Ð´Ð½Ð¾Ð³Ð¾ сигнала на несколько мс., с помощью исследования ПИ - регулятора + упреждения улучшили Ð¿ÐµÑ€ÐµÑ Ð¾Ð´Ð½Ñ‹Ð¹ процесс. А также был исследован фильтр в обратной связи в функциональной ÑÑ ÐµÐ¼Ðµ контура скорости.

Achieved studies the speed reference unit, namely fixed setpoint (unipolar and bipolar), ramp operation (motor - potentiometer). Chart speed smoothing has been studied, "Quick Stop". We studied the PI - at various time constants of the regulator, and the gains have come to the best option. The resulting version lags behind the input signal for a few milliseconds by PI studies + Feedforward control improved transient response. A filter was also examined in the feedback function diagram of the velocity loop.
