Time-varying systems

In the paper "Delay feedback control in exponential stabilization of linear time-varying systems with input delay", the authors investigate the memory controller design for the exponential stabilization of linear timevarying systems with control delay. Based on state transformation and an improved Lyapunov–Krasovskii functional, new sufficient conditions for the exponential stabilization of the system are derived to design memory feedback controller which makes the system exponentially stabilizable.

The electromagnetic power is generated and radiated by antennas. Timevarying current radiates electromagnetic waves (radiated electromagnetic fields). Radiation pattern, beam width, directivity, and other major characteristics can be studied using Maxwell’s equations, see Section 2.2. We use the vectors of the electric field intensity E, electric flux density D, magnetic field intensity H, and magnetic flux density B. The constitutive equations are D = εE and B = µH where ε is the permittivity; µ is the permiability. It was shown in Section 2.
