Abstract :
Eigenstructure assignment is a method which allows the incorporation of classical specifications on damping, settling time, and mode decoupling into a modern multivariable control framework. This method allows the designer to directly satisfy damping, settling time, and mode decoupling specifications by directly choosing the eigenvalues and eigenvectors. In this paper, we combine eigenstructure assignment with gain scheduling to obtain an algorithm which does not require the non-singularity of a matrix at a particular value of the parameter. The eigenstructure assignment gain scheduling computation is a direct non-iterative expression for the plant which was considered by Shahruz and Behtash (1992). For each value of the parameter the gain expression is a natural extension of the gain computation for the standard linear plant which was considered by Sobel et al. (1989)
