摘要：A control system for a heating system of an exhaust system is provided. Thecontrol system includes at least one electric heater disposed within an exhaust fluid flowpathway, and a control device adapted to receive at least one input selected from the

group consisting of mass flow rate of an exhaust fluid flow, mass velocity of an exhaustfluid flow, flow temperature upstream of the at least one electric heater, flow

temperature downstream of the at least one electric heater, power input to the at leastone electric heater, parameters derived from physical characteristics of the heatingsystem, and combinations thereof. The control device is operable to modulate power tothe at least one electric heater based on at least one input.
