Application of gain scheduled eigenstructure assignment to flightcontrol design

摘要

Eigenstructure assignment is a method which allows theincorporation of classical specifications on damping, settling time, andmode decoupling into a modern multivariable control framework. Thismethod allows the designer to directly satisfy damping, settling time,and mode decoupling specifications by directly choosing the eigenvaluesand eigenvectors. In this paper, we combine eigenstructure assignmentwith gain scheduling to obtain an algorithm which does not require thenon-singularity of a matrix at a particular value of the parameter. Theeigenstructure assignment gain scheduling computation is a directnon-iterative expression for the plant which was considered by Shahruzand Behtash (1992). For each value of the parameter the gain expressionis a natural extension of the gain computation for the standard linearplant which was considered by Sobel et al. (1989)
