A system includes an exhaust aftertreatment system and a controller including a processor coupled to a memory device storing instructions that, when executed by the at least one processor, cause the controller to perform operations. The operations include receiving sensor data comprising a diesel oxidation catalyst inlet temperature, a selective catalytic reduction system inlet temperature, and exhaust flow data; determining outer loop feedback data based on a target SCR temperature, and the SCR inlet temperature; determining inner loop feedback data based on the outer loop feedback data and the SCR inlet temperature; determining inner loop feedforward data based the outer loop feedback data, the DOC inlet temperature, and the exhaust flow data; determining heater control data based on the inner loop feedback data and the inner loop feedforward data; and causing the heater to operate in a stable manner while maintaining a stead desired temperature target.
A system, comprising:
A method, comprising:
A non-transitory computer-readable medium storing instructions that, when executed by at least one processor of a controller, cause the controller to perform operations comprising:
