Heating control arrangement for an electronic smoking article and associated system and method

摘要

A method is provided for controlling heating of an aerosol precursor arrangement of an electronic smoking article. An average power is directed from a power source to a heating device arranged to heat the aerosol precursor arrangement and a heating time period commensurately initiated. The average power corresponds to a selected power set point associated with the power source. An actual power directed to the heating device is determined as a product of a voltage at, and a current through, the heating device. The actual power is compared to the average power, and the average power is adjusted to direct the actual power toward the selected power set point. The actual power is periodically determined and compared to the average power, and the average power adjusted toward the selected power set point, until expiration of the heating time period. An associated apparatus and computer program product are also provided.

1. A method of controlling heating of an aerosol precursor arrangement of an electronic smoking article, comprising:
directing power from a power source to turn a heating device on to heat the aerosol precursor arrangement and commensurately initiating a heating time period; and at a periodic rate until expiration of the heating time period, determining a moving window of measurements of instantaneous actual power directed to the heating device, each measurement of the window of measurements being determined as a product of a voltage at the heating device and a current through the heating device; calculating a simple moving average power directed to the heating device based on the moving window of measurements a instantaneous actual power; comparing the simple moving average power to a selected power set point associated with the power source; and adjusting the power directed from the power source to turn the heating device off or on at the periodic rate at each instance in which the simple moving average power is respectively above or below the selected power set point.
