Abstract
A control system for a homogeneous charge compression ignition (HCCI) engine includes a fuel requirement estimation module, a torque estimation module, and a torque control module. The fuel requirement estimation module estimates a fuel requirement of the HCCI engine based on a desired indicated mean effective pressure (IMEP) of cylinders in the HCCI engine. The torque estimation module estimates a torque output of the HCCI engine based on the estimated fuel requirement. The torque control module adjusts the torque output of the HCCI engine based on the estimated torque output and a desired torque output.
