In order to solve the problem of track straight line and curve tracking control for under-actuated ships, Bech model is selected to solve the non-linear problems such as course instability. With the help of hyperbolic tangent function, the expected heading equation is constructed, and the track control problem is transformed into the heading control problem.

“Electrical Appliances and Programmable Controller” course is an important professional course of electrical and automation specialty. According to the characteristics of the course, this paper puts forward corresponding reform measures from two aspects of theoretical teaching and practical teaching. After implementation, students’learning initiative and engineering practice ability have been improved, and good results have been

A design of DDR2 controller for LCoS sequential color display is presented. The controller is based on AMBA AHB-Lite 3.0 protocol, in order to improve the system bandwidth. This paper analyses the hardware architecture of color-to-chronological color conversion in LCoS space. By storing a frame of RGB data into a bank of SDRAM, and reading

TFT-LCD is the first to enter the display market because of its low working voltage, low power, good display effect, easy integration and portability. In this paper, TFT-LCD display principle, system structure and timing controller TCON design scheme are described in detail. In high-resolution display system, the clock frequency is very high. Before generating timing

With the development of digital audio technology, broadcasting audiences are increasingly demanding to listen to radio programs. If audiences have obvious differences in sound quality when they change channels or multiple programs, audiences will regularly adjust the volume to a suitable level. How to keep the sound quality of all programs in a uniform level

This paper mainly studies the generation and composition of SNN unified controller based on ONOS architecture. The advantages of ONOS open source control platform are illustrated by the example of transmission Ethernet service line issuance. Starting from the characteristics of ONOS, this paper expounds that ONOS is suitable for operators’requirements for open source controllers. It

According to the domestic demand for the performance of air conditioning controller, an air conditioning controller based on Cortex-M4 is designed. It takes NUC472 as the main control core, and uses electric parameter monitoring sensor, flammable gas sensor, ionic smoke sensor, human pyroelectric infrared sensor, temperature sensor and temperature and humidity sensor to collect real-time

The excitation controller based on LPC11c14 completes the hardware and software design of frequency measurement, terminal voltage and synchronous shift trigger. The terminal voltage is obtained by AD sampling. The terminal voltage is compared with the given reference value as a control signal. The control voltage Uk is obtained by PID control processing, and the

In order to make the PLC controller conform to BACnet International Building Automation Control Standard, a PLC controller based on S TM32 control chip and MS/TP protocol is designed and developed. The controller can be programmed by ladder diagram and has complete control logic to meet the consistency requirement of BACnet. Experiments show that the
