Design of an Optimal Preview Controller for a Class of Linear Discrete-Time Descriptor Systems

Abstract EN

The preview control problem of a class of linear discrete-time descriptor systems is studied.

Firstly, the descriptor system is decomposed into a normal system and an algebraic equation by the method of the constrained equivalent transformation.

Secondly, by applying the first-order forward difference operator to the state equation, combined with the error equation, the error system is obtained.

The tracking problem is transformed into the optimal preview control problem of the error system.

Finally, the optimal controller of the error system is obtained by using the related results and the optimal preview controller of the original system is gained.

In this paper, we propose a numerical simulation method for descriptor systems.

The method does not depend on the restricted equivalent transformation.
