Abstract
A rate based model predictive controller and method for air path control for a diesel engine regulates intake manifold pressure (MAP) and EGR valve flow rate to specified set points by coordinated control of a variable geometry turbine (VGT) and EGR valve position. A decay and a flexible Lyapunov function is enforced on the rate based model predictive controller for a single step prediction and control arisen.
Claims20
A method for controlling an internal combustion engine having a controller controlling a variable geometry turbine and an EGR valve during engine operation comprising:
- using a rate based contractive predictive model in a controller responsive to engine intake manifold pressure and EGR valve flow rate, to generate requested engine turbine lift and requested EGR flow rate.
A method for controlling an internal combustion engine having a controller comprising:
- controlling a variable geometry turbine and an EGR valve during engine operation, using a computer program tangibly embodied on a computer usable medium and comprising instructions that when executed by a processor is functional to use a contractive rate based predictive model, responsive to intake manifold pressure and requested EGR valve flow rate, to generate turbine lift and EGR flow rate.
