For multi-input multi-output networked control systems with multiple independent sensors and actuators, thermostatic element a continuous-time model of a class of networked control systems with multiple time delays is established. By constructing a new Lyapunov function, a stability criterion with low conservativeness is given. Based on the stability criterion, the design method of output feedback

In view of the curriculum objectives and teaching characteristics of microcontroller technology for computer majors in Colleges and universities, project-driven teaching method can give full play to the leading role of teachers and the main role of students, effectively improve teaching efficiency and quality, and cultivate students’comprehensive ability in microcontroller technology curriculum. Microcontroller technology is

Aiming at the single point failure of control plane in SDN, a centralized network control environment, a controller architecture based on intrusion tolerance is proposed to improve network availability and reliability through redundant and diverse central controller platforms.The architecture detects intruded controllers using a method of comparing controller messages.Firstly, it specifies the key message types

With examples, the network node controller of theatre stage special lighting is discussed in some large theatres for reference. Stage-specific lighting network node controller successfully transforms the network lighting data into multiple serial port data by using the special lighting network protocol (sACN and Artnet) through data mapping of ethernet, and then synchronously distributes the

With the continuous development of modern computer technology, the automation technology and level of pumping stations in China are constantly improving, but there are also some problems and shortcomings in the practical application and operation of pumping station automation system. This paper presents an automatic pumping station system based on Intelligent controller, which is the

The automatic argon blowing system for ladle introduced in this paper takes the mass flow controller as the core, matches the corresponding hardware detection, software programming and so on. The pipeline and hardware modification, the signal connection between mass flow controller and computer are briefly introduced. It has been successfully applied to ladle bottom blowing

In recent years, network technology has developed rapidly, and has made great contributions to promote the development of various fields of production and life in society. The emergence of industrial Ethernet technology also makes it further integrated into the control layer and equipment layer of the control system network. In order to further promote the

[Abstract] SDN (Software Defined Network) is a new network architecture design concept proposed in recent years. Its basic attributes include separation of forwarding and control plane, centralized network control and open and flexible programmable interface. This paper introduces the concept of SDN technology, and expounds the logical architecture and network architecture of multiple SDN controllers.

LT3752, LT3752-1 and LT3753 are high-performance active clamp forward controllers with high integration, which can minimize the number of external components, solution size and cost reduction. LT3752 and LT3753 are used for up to 100V input, while LT3752-1 is used for applications with input voltage higher than 100V. Therefore, LT3752-1 is suitable for HV automotive

With the continuous improvement of coal mine modernization, the requirements for the stability, safety and uninterruptedness of underground power supply and distribution system in coal mine are becoming higher and higher. Most of the high and low voltage integrated protectors used in underground power supply have RS-485 communication interface, but the specifications are various, the
