The well-known generalized Kalman–Yakubovich–Popov lemma is widely used in system
analysis and synthesis. However, the corresponding theory for singular systems, especially …

In this letter, we prove that almost every infinite-horizon linear quadratic regulator (LQR)
control problem with single-input admits an optimal solution in the form of a feedback that is …

The eigenstructure of imaginary axis eigenvalues of a Hamiltonian matrix is of importance in
many fields of control systems, for example, in stability analysis of linear Hamiltonian …

As a kind of special stochastic system, multi-model jumping system has received in-depth
research, and a lot of innovative results have been achieved due to the profound influence …

Lossless trajectories of a passive system are the trajectories that satisfy the dissipation
inequality with equality. In other words, for a suitable input-state-output representation, these …

The well-known GKYP is widely used in system analysis, but for singular systems, especially
singular fractional order systems, there is no corresponding theory, for which many control …
