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 . |
