摘要：The present disclosure relates to a controller apparatus for regenerating aparticulate matter sensor. The controller apparatus includes a sensing module
configured to detect a soot loading on a particulate matter sensor and generate aregeneration request indicating a desired regeneration temperature and a heatingmodule configured to receive the regeneration request and send a heating commandsignal to a heating element based on the regeneration request. The controller apparatusalso includes an electrical resistance module configured to detect an electrical resistancein the heating element, a calibration module configured to determine an actual
temperature of the heating element based on a resistance-to-temperature model, and atemperature feedback module configured to modify the heating command signalaccording to the difference between the desired regeneration temperature and theactual temperature.
