Guaranteed cost reliable control with constraint of decay rate for uncertain time-varing delayed systems;

Then based on the MV model, which has some confined defects, for example, the psychological status are not correctly reflected, the model is ineffective when the return over not normally distributed, the author proposes that portfolio should be made by the maximum of following performance index: information rate and decay rate.

Based on the tool of state space method and the linear matrix inequality(LMI),the problem is transformed to the partial state feedback problem first,and the LMI criterion to judge is found and then if the given plant can meet the stabilization criterion,the algorithm to calculate the maximal attenuation degree of the closed-loop system and the lower bound for the steady-state output.

The design of multivariable PID controllers which guarantee the stability of closed loop systems,have a fixed attenuation degree,and robust performance specifications is described.

Consistency of decay ratio and H-infinity indices in PI control;

The problem of satisfactory PID control for a class of stochastic systems with constraints on desired opportunity-awaiting control characteristic indices and decay ratio index is considered.

The research and application about attenuation of envelope on residence of north village and small towns;

Robust controller with definite attenuation for a class of fuzzy time-delay systems;

This article analyzed different reason for the amplitude attenuation of the acoustic emission,and used the AE testing device produced by PAC America to test the acoustic emission attenuation using a pipe with many complex features.

A complete parabolic shear lag analysis containing delamination damage induced by transverse cracks was therefore proposed and applied to predict the stiffness reduction by transverse cracking of materials.
