Aiming at the problems of non-linearity, large lag and time-varying of water temperature change in aquatic greenhouse caused by large specific heat capacity of water body, thermostatic element considering the disadvantages of poor adaptive ability and weak robustness of traditional PID controller, a PID control strategy based on BP neural network is proposed. In this

In this paper, the characteristics of Si4010 and Si4463 RF chips developed by Silicon Laboratories and the design of remote control system for garage door controller are introduced. Provide reference for product development and other wireless application design in related industries. With the development of society, people’s living standard is constantly improving, and the purchase

This paper describes the design and implementation of a customized controller which can control AC servers instead of PC in some specific occasions. The controller uses only one CPLD as the main control chip, does not need MCU and external memory, and has simple peripheral circuit design. The parameters are configured and stored using FLASH

Automation, informationization and mutual you, you */ dynamic smart grids need a smarter network. SDN Software Definition Network (SDN Software Definition Network) can help the rapid development of intelligent power/network. OpenDaylight is an open source controller framework for SDN. It is easier to open and innovate SDN in a collaborative way and model driven architecture.

Aiming at the problem that the processing ability of software-defined network single controller can’t meet the requirement of scalability and that the current distributed multi-controller platform can’t change the service according to the actual situation, this paper puts forward the design of service abstraction layer at the control level, and tests the feasibility of the

Due to various reasons, students’ enthusiasm is not high and the experimental results are not ideal because of various reasons. In view of this situation, combined with the teaching strategy and characteristics of the technology based universities, the paper puts forward the supporting experiment improvement measures which are suitable for programmable controller principles and application

Taking fan controller in voltage regulator room as an example, this paper introduces the selection of devices in the design, the analysis of the control circuit principle, the production and debugging, and provides a reference for you. Introduction: Although the high voltage in the transmitter is a dedicated line, the 380VAC voltage varies frequently due

This paper mainly introduces the design technology of triangular wave signal output by using programmable logic controller to generate digital signal and special A/D and D/A conversion module. At present, in many automatic control systems, PLC is often used as the control equipment for data acquisition, state discrimination and output control. This paper introduces the

With the continuous development of social economy, China has gradually entered the era of industrialization. According to the requirements of the four modernizations, the mainstream direction of industrial development in the future is to achieve modernization. 　　The realization of industrial modernization must be supported by electrical automation technology. Programmable controller is an advanced controller, which

Programmable Controller Course is an optional course for mechanism majors. In view of the phenomenon that mechanism majors generally separate “machine” from “electricity”, this paper proposes to combine “Programmable Controller Course” with mechanism majors, and stimulate students’interest in learning “Programmable Controller Course” by reforming teaching links. As an industrial control device rising in the 1980s,
