【Abstract】 From the theoretic analysis of dynamic response of FCS, the main concepts of eigenstructure assignment as a design method are presented, which in corporates a briefly description of how to determine a desired eigenstructure based on design specifications, and mathematical process of eigenstructure assignment itself, for the design of complicated FCSs. This method can directly satisfy specifications in terms of transient response and modes decoupling. In spite of the controller simplicity, good performance including robusteness can be obtained. It is comparable to classical methods, where the relation between the system output and the actuation demanded is visible to the designers.更多还原
