1. A combustion control system for a turbulent jet ignition (TJI) engine having a first ignition device disposed in a pre-chamber of a cylinder head and a second ignition device disposed for communication with a main combustion chamber, the system comprising:
a set of sensors configured to measure operating parameters; and
a controller configured to:
access a trained feedforward artificial neural network (ANN) configured to model a first spark from the first ignition device, and maximum brake torque (MBT) spark based on the operating parameters;
generate the first spark, and the MBT spark for the engine using the ANN with the measured operating parameters from the set of sensors as inputs;
generate a second spark for the second ignition device;
determine a target spark timing for the engine based on at least one of the first spark, second spark and MBT spark.
