摘要:

Explicit results on solution, stability and reduction of a class of discrete-time linear time-varying systems are presented. It is shown that the state transition matrix can be computed explicitly by φ(k,0)=A1kA2k,whereA1andA2are constant matrices. The stability is completely determined by eigenvalues ofA1andA2. It is also shown that the system can be reduced to a time-invariant one by an algebraic transformation. Examples are given to show that stability criteria of linear time-invariant systems cannot, in general, be applied to time-varying cases.

摘要:

The problem of observing the state vector of a multivariable system subjected to inaccessible inputs is considered. Using a polynomial-type approximation for these inputs, a set of necessary and sufficient conditions that can be readily applied to determine the existence of an observer is obtained. Computer simulation results for a third-order two-input, two-output system are included.
