This thesis contains a formal mathematical investigation of clutch engagement in automotive vehicles. This investigation is conducted by developing a model of an automotive powertrain, and investigating undesirable effects that can occur in clutch engagement. This naturally leads to the development of a multi-objective optimal control problem describing how to best to engage a clutch. An algorithm for solving this optimal control problem is then presented. Arguments for the development of a feedback control strategy are then discussed, with the construction of such a feedback strategy, along with the computations required to evaluate the feedback controls detailed. A further extension, of adapting the feedback controls, to cope with powertrain model perturbations then follows, along with a method of estimating such perturbations. Finally, the use of this research in implementing clutch engagement control is outlined. Throughout the thesis, the various control strategies designed are evaluated by carry out simulations of models representing the powertrains of two different family cars.
