REALIZATION ALGORITHM FOR TIME-VARYING SYSTEMS
IFAC Proceedings Volumes, 1987Abstract This paper considers the problem of modelling discrete-time multivariable time-varying systems applying the results of stochastic realization theory for real data. A method is given for determining Eee T /of the error process e(t) of Kalman filter/by the output covariance function in an explicite way.

Prediction for time-varying SVD systems
2004 IEEE 15th International Symposium on Personal, Indoor and Mobile Radio Communications (IEEE Cat. No.04TH8754), 2005The performance of a system using singular value decomposition (SVD) over a multiple-input multiple-output (MIMO) channel is dependent on the accuracy of the channel state information (CSI) at both the transmitter and receiver. In time division duplex (TDD) systems the reciprocal nature of a channel means that the CSI obtained during the uplink can be ...

Identification of time-varying Hammerstein systems
1995 International Conference on Acoustics, Speech, and Signal Processing, 2002We consider the identification of systems which are both time-varying and nonlinear. This class of systems is more likely to be encountered in practice, but is often avoided due to the difficulties that arise in modelling and estimation. We attempt to address this problem by considering a new time-varying nonlinear model, the time-varying Hammerstein ...

A complementary view on time-varying systems
ISCAS 2001. The 2001 IEEE International Symposium on Circuits and Systems (Cat. No.01CH37196), 2002This contribution is complementary to a previous approach by the authors in that it takes a time-varying mode-vector solution as an a priori assumption. The associated dynamic eigenvalue problem is solved by triangularizing the system equations, again accomplished by successive Riccati transforms.

Demystifying Time Varying Circuits and Systems
2016 29th International Conference on VLSI Design and 2016 15th International Conference on Embedded Systems (VLSID), 2016An analog/mixed-signal/RF designer encounters time varying circuits everywhere - sample-and-holds, chopper stabilized amplifiers, mixers, switched-capacitor amplifiers and filters, discrete and continuous-time delta sigma modulators, mixers, N-path filters, oscillators : the list is endless.

Time-varying systems and crossed products
Mathematical Systems Theory, 1984Crossed product algebras are proposed as a framework for the study of input-output properties of linear time-varying systems. It is shown that internally stable systems with bounded continuous coefficients have transfer operators in a crossed product and conversely, that the set of all such transfer operators is dense in a crossed product.

Stabilization of time-varying Hamiltonian systems
IEEE Transactions on Control Systems Technology, 2006This paper investigates the stabilization problem of time-varying port-controlled Hamiltonian (PCH) systems through energy-shaping. First, the closed-loop form of a time-varying PCH system (with certain feedback) is embedded into an extended system.

Inclusion principle for time-varying systems
Proceedings of the 40th IEEE Conference on Decision and Control (Cat. No.01CH37228), 2002The inclusion concept is applied to dynamic time-varying linear continuous-time systems. Starting from general definitions, which include restriction and aggregation as special cases, inclusion conditions are derived. Properties of different inclusion types are discussed.
