A new algorithm for computing the state vaiable feedback gain;

Lyapunov Equation based algorithm for calculating state feedback gain is a comparatively normal algorithm used in pole assignment.

The concepts of equilibrium solution, initial variation and feedback gain of circuit variables are introduced.

To deal with the problem of extreme expanded operation quantity of backstepping method,a method of simplifying design by using high-gain feedback to dominate differential items of virtual inputs was introduced.

This article describes the affection to the whole product,which is because of injecting a perturbation signal into feedback loop, to evaluate the stability,then by the use the frequency response analyzer equepiment gets an accurate result,and the result is used for improvement,as well as improve the products reliablity.

In this paper we discussed a feedback loop for carrier frequency offset synchronization in orthogonal frequency division multiplexing (OFDM) systems.

These clock genes and their products consist of two interlocked transcriptional/translational feedback loop, which regulate circadian rhythms of behavior and physiology in Drosophila.

A new desuperheating water valve has been designed accordingto the principle that the flow characteristic of the valve matching the loop gain of the control system should bea constant.

By adopting a simple and easy, we get the calculation formula of common-emitter and common-base configuration loop gain of oscillator circuit of three-point capacitance, hence work out an improved design of quiescence collector current and feedback.

Traditional loop gain simulation method is based on two-port network models,which is complex to analysis and it is not suitable to get quantitative analysis of the loop gain fast.
