The diesel engine in a submarine is subject to time varying exhaust manifold pressure disturbances caused by waves, which leads to undesirable surging of engine speed and temperature when a conventional speed governor approach is used to schedule the engine inputs. In this talk, a variant of MPC will be investigated as a possible approach to reduce these fluctuations whilst maintaining critical state constraints in the presence of model uncertainty and system disturbances. The proposed approach is experimentally demonstrated on a modified engine dynamometer, and is shown to be a useful way of identifying suitable actuator combinations under different scenarios. It is also shown that the related problem of series hybrid powertrain control in the automotive domain can be formulated and handled in a similar fashion.
