A system for controlling an electrostatic precipitator (10, 12) adapted to be powered by an alternating power source (60) includes means for regulating (Q2, Q4, 14) at least one precipitator operating parameter in response to at least one control signal, and measurement means (110, 120) coupled to the precipitator for providing measurement signals corresponding to at least precipitator secondary voltage and precipitator secondary current. A processing means (16) coupled to the measurement means (110, 120) and to the means for regulating generates the control signals. The processing means (16) is operable to sample successive discrete values of the measurement signals corresponding to secondary voltage and secondary current during an individual half cycle of the alternating power source (60), to determine present precipitator (10, 12) operating conditions based on at least the sampled values, to predict precipitator (10, 12) operating conditions for the next half cycle of the alternating power source (60) based on at least the present operating conditions, and to selectively vary said at least one control signal by the next half cycle of the alternating power source (60) in response to the predicted operating conditions. |
