Abstract
A system and related method for cleaning a particulate filter medium. The filter medium is cleaned by the input of energy to burn off particulate matter collected thereon. The system can comprise a thermocouple for monitoring the temperature of the filter medium at a plurality of locations. There is an electronic control unit for determining the point having a maximum individual temperature and creating a control signal commensurate with the maximum temperature. The control unit can determine if the control signal exceeds a predetermined set point level and if so reduces the energy input. The control unit also determines if the control signal falls within a predetermined range, also referred to as a band width of acceptable values less than the set point level. If the signal falls within the band width, the control unit controls the energy input and varies it as appropriate in order to maintain the control signal within the band width.
