Feedback Time

In this paper the minimal overshoot and settling time of error-sampled feedback time-delayed control systems was carried out by incorporating a digital controller in the forward path of the control loop. Using the state-transition method the controller was designed by applying the variable-gain approach. The effect of parameter variation on the compensated response is also studied.

Improved Characteristics

A fundamental diagram of a control system for missiles of various classes is investigated. A functional diagram of a control system with an intelligent component for long-range aerodynamic rockets returning to the atmosphere is developed. It is proposed to use in the control loop an ensemble of a priori missile models and models of external influences. It is proposed to improve the accuracy of control systems with an intelligent component by increasing the degree of controllability of the state variables for a priori models. The most convenient numerical criterion of controllability degree for of the state variables of the models is presented. The results of mathematical modeling showed a slight increase in the efficiency of missile control with an increase in the degree of controllability of the pitch angle by changing the coefficients of the control matrix.

POWERED Hying controls have been fitted to aircraft for more than 20 years and with larger or faster types—both aeroplanes and helicopters—have become almost taken for granted. But their form can vary considerably and the present is a good time to take a long look at some of the factors which govern the system adopted.

A 10Gbit/s burst-mode transimpedance preamplifier is described. Regulated cascade (RGC) TIA core with variable gain, fast response peak detector, single-to-differential and output buffer are included, providing auto-gain-control and threshold extraction functions. The burst-mode preamplifier is implemented by 0.13µm CMOS technology, presents a high gain of 67.9dB with a 3-dB bandwidth of 6.92GHz and a low gain of 57.4dB with a 3-dB bandwidth of 8.60GHz with a settling time less than 20ns.

The development of artificial intelligence accelerated the development and application of smart sensors and human observation and study systems, and the establishment of continuous monitoring of it using various sources. The financial industry has always sought to collect as much data as possible about its customers. Many countries have begun to create population control systems. China leads the development of such a system. In 2020, Russia launched a digital citizen profile system, which should ensure high-quality interaction between the population, the business community and the state through the collection, processing, archiving and analysis of information from public and private sources. How the system will be used: in the name of Good or Evil depends on those who make the decision and use it. The main carrier of information about oneself is the person himself.
