随着我国高等教育规模的不断扩大,高等教育已由精英教育逐步向大众教育方向转变。教育对象发生了较大的变化,应用型人才的培养已经成为一批院校的培养目标。为了更好地适应当前我国高等教育跨越式发展的需要,满足社会对高校应用型人才培养的需求,全面提高应用型人才培养的质量,编写适应应用型人才培养的专业教材是很有必要的,具有积极的意义和实用价值。“电力传动自动控制系统” 是自动化类专业领域各个专业方向的一门重要的专业课程。为适应应用型人才培养需要,专业理论课程的学时数大幅精简,课程内容与学时之间的矛盾更显突出,这就要求课程使用的教材在篇幅上做必要精简,内容上做合理调整。目前适用于应用型人才培养的本门课程的教材较少,大部分*教材面向普通高等院校,这类教材对于培养应用型人才的院校来说,起点较高、难度较大、内容较多,难以适应教学需要。本书正是出于上述考虑而编写的一本新的“电力传动自动控制系统”教材。根据应用型人才培养目标和教学要求,基本理论应基本到位,重点突出技术的分析和实际应用。本书在编写的过程中,对相关内容做了删减与调整:遵循“少而精”的原则,适当删减部分理论性强又较为抽象的内容,增强教学内容的针对性和实用性;结合“重实践”的要求,在基础部分重点突出直流控制系统和交流控制系统的特点、负载的特点以及控制功能,在实际应用部分,通过实例加强基本原理及应用的分析。本书由陈三宝教授主审,武汉城市学院蔡晓燕担任主编,武汉城市学院陈媛、武汉晴川学院陈玲、武汉城市学院胡娜、武汉城市学院余秋月担任副主编。武汉理工大学、武汉科技大学电气工程及其自动化专业的相关教师对本书的编写提出了富有建设性的建议,在此表示衷心的感谢!本书编写过程中参考了国内相关出版社的教材和部分专家的论著,在此谨向相关的作者致以衷心的感谢。为了方便教学,本书还配有电子课件等教学资源包,可以登录“我们爱读书”网(www.ibook4us.com)浏览,任课教师还可以发邮件至hustpeiit@163.com索取。由于编者水平有限,编写时间仓促,书中难免存在错误和疏漏之处,恳请广大读者批评指正。编者2021年6月
