PLC在电气自动控制中的应用

随着电气控制技术的发展和计算机技术的广泛应用，单片机逐渐取代传统逻辑开关，但是单片机技术复杂，编程难度高。而可编程控制器，它以控制功能强大，通用性好，编程简单易操作，控制稳定等特点正在成为电气自动控制系统中重要的开关量逻辑控制元件，并结合，声、光、电、液等信号采集元件和变频伺服技术成为电气自动控的核心部件。     

《毛泽东思想和中国特色社会主义理论体系概论》教学改革探讨

“概论”课理论性、现实性很强,在当前我国社会转型和改革攻坚深刻影响人们思想的形势下,如何讲好“概论”课对教师的教学理念、教学方法、技能和知识结构都提出了很高的要求.笔者在认真分析学生对思想政治理论课需求的基础上进行了一系列教学方法改革和实践：坚持理论联系实际,讲好讲活理论；采取互动教学方法,让学生更多的参与教学；灵活运用多媒体技术；通过实践教学促进课堂教学；举办多种专题讲座,拓展学生思维和视野.     

宽幅高效离心式双圆盘撒肥机设计与试验

为解决现有水旱田撒肥机械作业效率低、撒肥量调节技术落后、施肥均匀性稳定性差等实际问题,设计了一种同轴驱动的离心式双圆盘撒肥机。介绍了整机结构与工作参数,研究设计了撒肥传动系统、撒肥盘结构、排肥量液压调节装置等,并确定了关键结构和参数,同时进行了试验研究。试验结果显示,推肥板推肥角度-20°~30°可调,撒肥幅宽达到50m,总排肥量稳定性变异系数低于6%,施肥均匀性变异系数低于16%。研究结果表明,撒肥机工作性能稳定、撒肥量可控、抛撒均匀,整机设计满足水旱田宽幅高效撒肥作业要求。     

ICAI Realizaltion for the K-map Simplification of Logical Function

Based on the theory of the K map simplification of logical function(KSLF),this article releases a ICAI Realization for KSLF.Providing three kinds of teaching style:commonness, teaching, practice.This product,wich supports for the K map simplification with random item,is not only helpful to the construction of the curriculum of digital circuit ,but also to the design for digital application system.Under the practice method, This product's guides,checks,and corrects the student's whole process forthe proceeding of KSLF automaticly under the teaching method.     

An Expert System Approach to the Computer Aided Design of Intelligent Controllers

The idea for an expert system approach to the computer aided design of intelligent controllers (ESCAD1C) is discussed and the idea of two step modelling of an intelligent controller is presented on the basis of emulating human control behaviours to solve complex problems. The structure, functions and characteristics of ESCADTC system , and the design procedures of intelligent controllers are gived. The knowledge base and simulating functions for designing intelligent controllers are also described.     

Using BP Neural Network to Determine the Membership Function of the Input of Fuzzy Control System

While design the fuzzy controller, it is very important to determine the membership function of fuzzy variables.The data can be broadly classified as fuzzy sets by using the classification property of the BP neural network. The author selects a BP neural network with one hide layer and uses S function to the input and hide layer, and linear function to the output layer.Advanced BP algorithm isused to train the BP neural network in the environment of MATLAB . The nearer to the target values is the better the last output is.With the trained BP network , the membership values of the inputs can be got ten. This method has high rate and low error.     

A Study on the FMS Planning and Scheduling System

After researching the function requirements of the planning and scheduling in manufacturing cells, the paper advanced a control structure with three phases, i. e. planning , scheduling and dispatching. The paper represented in detail the main purposes, requirements and scheduling actions in each phase. It suits to general machining FMSs.
