Résumé: One of the most popular techniques used to design the dynamics of a system is state feedback. In the case of multivariable systems, the feedback gain matrix permitting the assignment of the desired set of closed loop poles is not unique. Helicopters represent a good example of complex multi-input multi-output systems as they are inherently unstable, highly cross-coupled and very non-linear. The objective of this thesis is to compare and evaluate two design methodologies, based on canonical forms: block pole design and pole placement, for the case of a Lynx helicopter model at Hover. The study is conducted through the simulation of large number of possible state feedback gains .The initial condition response of these cases are plotted , the time response characteristics , gain matrices , performance and robustness measures are computed .These results are then compared to select the study cases with the smallest feedback gains and best time response and robustness performances .
