In this paper, self-tuning PI speed controller is used in active queue management algorithm. An active queue management algorithm based on self-tuning PI controller is proposed. The algorithm can achieve self-tuning of controller parameters. The simulation results show that the algorithm has faster response speed and smaller “steady-state error” than the active queue management algorithm

Radio Frequency Identification (RFID) is a non-contact automatic identification technology. 　　It automatically identifies target objects and acquires relevant data through radio frequency signals. RFID technology can identify high-speed moving objects and identify multiple tags. 　　It is fast and convenient to operate. Long-distance radio frequency is not afraid of dust pollution. Video identification technology is applied

Nowadays, SDN, as a hot word in the industry, often enters people’s field of vision, and even is named as the general trend of the current industry. The emergence of SDN prompted the redefinition of network architecture. By decoupling the control plane and the forwarding plane, the network resources were pooled, which completely changed the

Electrical Control and Programmable Controller (PLC) is a practical technical application specialty course. 　　Firstly, the teaching content and syllabus requirements are optimized to meet the training objectives of applied talents; secondly, combining advanced teaching methods, improving teaching methods and assessment methods, focusing on strengthening the cultivation of students’ability to think independently and solve problems; finally,

[Absrtact] For high-order process objects with RHP zeros, the internal model controller can not be designed according to the general controller design method of first-order plus pure-lag process. Simply using the method of inverse plus filter for the object model, the problem of converting the right half plane after inverse into unstable poles must also

In the architecture of Software-Defined Networking (SDN), the controller is the core component of the control layer and plays a vital role in the performance of the network.In this paper, the structure and performance of SDN controllers are compared and analyzed, and the structure and technical characteristics of centralized control based on single control and

In China, there are few theoretical studies on the combustion of biomass briquette fuel. The study on the combustion mechanism and dynamic characteristics of biomass briquette fuel has just begun. The theory and data on the combustion of biomass briquette fuel have not been systematically put forward. 　　Straw manufacturing equipment was first introduced in the

Aiming at the requirement of middle aged people to economize water, thermostatic element save electricity, operate simply and cost more, an automatic washing machine controller based on single chip microcomputer is designed. In order to meet the requirement of easy use, the washing machine is completed automatically from washing, rinsing and drying, and automatic control

In the teaching process of microcontroller, it is often difficult to achieve ideal teaching effect by using theory alone. Usually, the teaching method combining theory with practice can improve students’understanding ability and cultivate students’ practical ability. In the case of limited hardware practice conditions, the teaching method of combining theory with practice will also be

Controller Area Network (CAN) is widely used in the automotive industry and is one of the most promising fieldbus. In recent years, CAN technology has been widely used in imported cars and domestic cars, marking a new era of automobile electronic control technology. This paper introduces the characteristics, composition and communication rate setting of controller
