Actuator controller has an important application in robot control technology. Its performance is directly related to the normal operation of multi-actuator system. In order to solve the contradiction between multi-output and high precision of servo controller designed with control chip, a new servo controller is designed. The hardware adopts high performance STC15F2K60S2 single chip computer,

LM555 is a widely used analog-digital hybrid (i.e. bipolar) integrated circuit. Based on the LM555 control circuit, this paper studies the timing and control integrated circuit. LM555 timer constitutes a multi-resonant oscillator. In the control circuit, the duty cycle of output waveform is regulated by the potentiometer, and the start-stop time of load operation is

Programmable controller is essential in industrial control, so PLC course is a very important professional course. This course requires logical thinking, and we know that PLC has many programming methods, such as instruction list, ladder diagram and sequential function diagram. Because everyone has different thinking modes, the implementation of each project is also different. 　　Today,

In this paper, the author visited DEVI (Denver, the world’s largest supplier of heating equipment and control parts) in Denmark in March 2003 to investigate the intelligent control manufacturing technology of floor radiant heating system, and combined with the customer feedback of the intelligent heating system temperature controller installed and used in Shanghai area for

Biomass stove is an energy-saving stove with biomass as fuel. It is a multi-variable input and output control system with pure lag and time-varying thermal inertia. Aiming at the problems of low combustion efficiency of biomass and large emission of harmful gases, a hybrid controller combining PID control and fuzzy control is designed by using

At the “2018 China Semiconductor Market Annual Conference and IC China Summit”, three local memory or memory controller manufacturers that have mass-produced chips introduced the relevant market technology trends and product strategies.These three enterprises are: Beijing Zhaoyi Innovation, Shanghai Hualan Microelectronics and Beijing Yixin Technology.Mr. Su Zhiqiang, Director of Strategic Marketing Department of Beijing Zhaoyi

This paper introduces an excellent external lighting scheme for automobiles by using high power Buck LED controller. 　　Thanks to excellent lighting characteristics and efficiency, high-power LED is becoming more and more popular in automobile external lighting design. Electronic devices supporting LED must be fast, efficient and accurate to control illumination intensity, direction and focus. These

With the continuous development of social science and technology, the ecological environment we live in has been gradually destroyed, such as more and more serious haze, greenhouse effect and so on. Nowadays, our country advocates low-carbon travel. Our country spends a lot of financial and material resources to develop and use clean energy to gradually

In order to solve the problem that paper surface defects (paper defects) are not easy to identify in the production process of medical test paper, a medical test paper disease detection system based on NJ controller is designed by analyzing the main characteristics of manual detection methods and paper defects. The system is composed of

This paper designs a shunt controller based on dynamic hashing algorithm. After the remote deployment of the router is completed by using Telnet component, the traffic data of each router is acquired in time through SNMP component, and the current variables are managed. The command files are fed back to each router through TFTP server,
