For a class of networked control systems with time-varying state delays and parameter perturbations in the model, by constructing input delays and adding free matrices, using Lyapunov functional and linear matrix inequality tools, the robust asymptotic stability of the closed-loop system and the time-delay conditions satisfying the given H_ disturbance rejection level gamma are obtained,

In view of the complex and expensive design and manufacture process of the existing PLC, which is not suitable for small batch production and manufacturing, a low-cost and simple PLC is designed to design the hardware structure and debug the system software.Through practice, it can be used to control mechanical equipment with certain work engineering,

The transmitter controller is an important part of the broadcasting transmitting system. Its main function is to monitor and control the working state of the transmitter. It is of great significance for the normal operation of the broadcasting transmitting system. Starting from the function design of the controller of the broadcasting transmitter, this paper studies

DK-2 braking system is an important part of HXD1 locomotive, and the mechanical locking structure is very important in the end-changing operation. Based on the analysis of the actuality of mechanical locking structure of brake controller, the concrete measures of optimum design are put forward. Through optimum design of mechanical locking structure, the size and

Aiming at the characteristics of complex control structure, variable working conditions, large inertia and strong coupling of boiler combustion system in thermal power plant, a control method of boiler combustion system based on Improved Fuzzy PID controller is proposed. Particle swarm optimization (PSO) is used to optimize the adjusting factor of the fuzzy controller on-line,

Practice teaching is the core link of training applied talents. Aiming at the shortcomings of traditional practice teaching of PLC, such as poor standard, poor design, and less exercise for students’ practical ability, this paper proposes practical engineering teaching reform based on engineering, and designs related experimental equipment and teaching materials. At the same time,

The integrated course design of programmable controller control system design and debugging is a comprehensive applied course implemented according to the requirements of enterprises for high-skilled talents and the actual requirements of enterprises’production.The course takes the enterprise practical project as the main line, with high and new technology as the support, and the brand-new integrated

The application of programmable logic controller (PLC) in the automation of microprocessor-based relay protection is quite common. It has many advantages, such as convenient programming, easy debugging, convenient docking, high stability and so on. The application of PLC in microprocessor-based protection is discussed in order to provide some reference. Under the background of the continuous

In game console, the Xbox series accessories are the best support for Windows. The current mainstream operating system Windows 10 can map the host content to the computer, thermostatic element and the Xbox One handle can also seamlessly connect to Windows. 　　Not only that, but there are also novel ways to use third-party tools such

With the continuous development of computer application and network technology, the risks and losses of information security are increasing exponentially, which leads to the increasingly prominent network security problems. According to the current situation of network security, this paper puts forward the idea of using network security controller to help solve network security problems, and
