Abstract :
This paper is concerned with the assignment of a desired eigenstructure to linear parameter-varying (LPV) systems as an extended version of the corresponding eigenstructure assignment problem for linear time-invariant systems. Based on a complete parametric solution of parametric generalized Sylvester matrix equation, a controller design method is proposed to guarantee a low sensitivity of the closed-loop eigenvalues. The observer state feedback structure is considered for output feedback control design. An example of control for a satellite attitude system is used to demonstrate the usefulness of the proposed approach.
