Abstract
A system for controlling regeneration in an after-treatment component comprises a feedback module, an error module, a gain module, and a regeneration control module. The feedback module is configured for determining a rate of change of the value of a controlled parameter. The error module is in communication with the feedback module and is configured for determining a value of an error term by subtracting a value of a target parameter from the value of the controlled parameter. The gain module is configured for determining a value of a proportional gain factor by raising a mathematical constant “e” to the negative power of the value of a tuned gain exponent and for determining a value of a derivative gain factor by multiplying the value of the proportional gain factor by a tuning factor. The regeneration control module is configured for determining a value of a rational control increment.
