⏹随着现代工业自动化要求的不断提高，电动执行器（尤其是智能型电动执行器）广泛进入了各个行业和领域。
⏹电动执行器可输出不同行程的转角和直线位移，控制阀门、风门等设备，对管线内流体的流量、压力等过程参数进行控制。
⏹不夸张地说，现代工业现场中有管线的地方就有电动执行器的身影。
⏹因此，工业现场过程控制需要电动执行器，电动执行器的选型也必须从现场工况出发！电动执行器选型的基础信息必须从实际工况中获得！只有这样，产品才能最好的为工业现场服务！电动执行器选型的基础信息⏹工况配置的是什么形式的阀门？⏹工况配置的阀门所需转矩或推力是多少？⏹工况配置的阀门与电动执行器采用何种方式连接，连接尺寸是多少？⏹工况要求阀门全行程（从开到关）动作所需的时间是多少？⏹工况能够提供什么标准的动力电源？⏹工况要求电动执行器达到什么样的防护标准？⏹工况要求电动执行器采用什么方式控制？有哪些控制和保护的要求？⏹工况或用户的其它要求？电动执行器选型的基础信息 工况配置的是什么形式的阀门？闸阀、截止阀等由阀杆带动启闭件沿阀座密封面做升降运动的阀门一般采用多回转输出的推力型电动执行器。
球阀、蝶阀等启闭件绕垂直于通路的固定轴旋转的阀门一般选用部分回转输出的转矩型电动执行器。
阀门的形式决定电动执行器输出的形式调节阀等靠垂直推拉阀杆改变流体通道面积，以改变流体流量的阀门一般用直行程输出的频繁调节型电动执行器。

执行器的工作原理及结构
一、概述 执行器在现代生产过程自动化中起着十分重要的作用。人们常把它称为实现生产过程 控制的手足，因为它在自动化控制系统中接受调节器的控制信号，自动的改变调节变 量，达到对被调参数（如温度、压力、流量、液位等）进行调节的目的，使生产过程 按预定要求正常进行。 执行器根据执行机构使用的能源不同可可分为气动、电动和液动三大类。 电动执行器 电动执行器是以电能为动力的，它的特点是获取能源方便，动作快，信号传递速度快， 且可远距离传输信号，便于和数字装置配合使用等。所以电动执行器处于发展和上升 时期，是一种有发展前途的装置。其缺点是结构复杂，价格贵和推动力小，同时，一 般来说电动执行器不适合防火防爆的场合。但如果采用防爆结构，也可以达到防火防 爆的要求。 气动执行器 气动执行器是以压缩空气为动力的，具有结构简单、动作可靠稳定、输出力大、维护 方便和防火防爆等优点。所以广泛应用于石油、化工、冶金、电力等部门，特别适用 于具有爆炸危险的石油、化工生产过程。其缺点是滞后大，不适宜远传（150m 以内）， 不能与数字装置连接。 目前，国内外所选用的执行器中，液动的很少。 执行器的基本结构 执行器由执行机构和调节阀（调节机构）两个部分组成，执行机构是执行器的推动装 置，它根据控制信号的大小，产生相应的推力，推动调节阀动作。调节阀是执行器的 调节部分，在执行机构推力的作用下，调节阀产生一定的位移或转角，直接调节流体 的流量。 为了保证执行器能够正常工作，提高调节质量和可靠性，执行器还必须配备一定的辅 助装置。常用的辅助装置有阀门定位器和手轮机构。阀门定位器利用反馈原理改善执 行器性能，使执行器能按调节器的控制信号，实现准确定位。手轮机构用于直接操作 调节阀，以便在停电、停气、调节器无输出或执行机构损坏而失灵的情况下，生产仍 能正常工作。 二、气动执行机构 气动执行机构接受气动控制器或阀门定位器输出的气压信号，并将其转换成相应的推 杆直线位移，以推动调节阀动作。

汽车传感器ECU执行器的关系概述
汽车传感器ECU执行器的关系概述1.1 电子控制组件（ECU）ECU以微机为中心。
还包括前置的A/D转换器、数字信号缓冲器以及后置的信号放大器等。
微机运算速度快、精度高，能实时控制，并具备多中断响应等功能。
目前除了8位、16位微机外，32位特别是64位微机已开始逐步使用。
而且，不仅有通用型微机和单片机，专用的汽车微机也已研制出来。
正是微机技术突飞猛进的发展促进了汽车电控技术的不断完善。
可以说，当前 ECU的发展总趋势是从单系统单机控制向多系统集中控制过渡。
不久以后，汽车电控系统将采用计算机网络技术，把发动机电控系统、车身电控系统、底盘电控系统及信息与通信系统等各系统的ECU相联结，形成机内分布式计算机网络，实现汽车电子综合控制。
实物如图1-1所示ECU实物图（1-1）1.2 传感器工作条件非常苛刻的汽车传感器，传感器可以准确地*工作是必不可少的。
近年来，在这一领域，理论研究和材料应用的发展是比较快速的，金属薄膜半导体技术，陶瓷烧结技术的快速发展。
毋庸置疑，智能、集成和数字化将成为未来传感器发展的趋势。
如氧传感器、机构1-2，图1-3中的实物图。
氧传感器结构图（1-2）氧传感器实物图（1-3）1.3 执行器为准确执行器执行由ECU信号发出的命令。
因此，执行器将准确地工作或不影响电子控制的成功或失败，这就是为什么他们的可靠性和准确性一直工作作为一个研究的重点，并吸引了更多的关注。
目前，电动汽车电子控制系统、电磁阀、电机、压电元件、点火、电磁继电器、热电偶、结构和功能各不相同的执行器类型范围。
致动器的发展方向是智能执行器和智能功率固态器件。
总结：电子控制系统由传感器、电子控制单元（ECU）、执行器3部分。
为输入传感器测量物理信号（温度、压力等），将其转换为电信号；ECU的作用是接收来自传感器的输入信号，根据设计方案的计算处理，输出处理结果；执行器ECU根据电气信号输出驱动器使要求的变化。

控制 – 学习控制
怠速控制阀的控制内容
起动初始位置的设定：关闭点火开关发动机熄火后，电子 控制单元ECU的M-REL端子向主继电器延续供电2～3s， ECU控制步进电机ISCV全部打开，以利于下次起动。
• 图中画出的是定子为两相集中绕组(AO、 BO)， 每 相为两对极， 转子磁钢也是两对极的情况。
• 从图中不难看出， 当定子绕组按A - B - (-A) - (-B) - A …… 轮流通以直流电时， 转子将按顺时针方向 转动， 每次转过45°空间角度， 也就是步距角为 45°。
• 一般来说， 步距角的值为
• 转子磁钢充磁后， 一端(如图中A端)为N极， 则A端转子铁心的整个圆周上都呈N极性， B 端转子铁心则呈S极性。 当定子A相通电时， 定子1 - 3 - 5 - 7极上的极性为N - S - N - S， 这时转子的稳定平衡位置就是图所示的位置，
即定子磁极1和5上的齿在B端与转子的齿对齐， 在A端则与转子槽对齐， 磁极 3 和 7 上的齿与 A端上的转子齿及B端上的转子槽对齐， 而B 相 4 个极(2、 4、 6、 8 极)上的齿与转子齿都 错开1/4齿距。
电动执行器有五种类型
电动执行器有五种类型：直行程电动执行器、角行程电动执行器、电动调节阀、PID电动调节执行器和电磁阀。
前四种属于DDZ型。
下面简要介绍一下直行程电动执行器(DKJ)和角行程电动执行器(DKZ)。
直行程与角行程电动执行器的作用是接收调节器或其它仪表送来的0~10，4~20毫安或1~5伏电压的标准值流电信号，经执行器后变成位移推力或转角力矩，以操作开关、阀门等，完成自动调节的任务。
这两种执行器以前都是由伺服放大器与执行机构两大部分组成的。
现在有机电一体智能化的结构，它们的结构、工作原理和使用方法都是相似的，区别仅在于，一个输出位移(推力)，一个输出转角(力矩)。
电动执行器选型考虑要点一、根据阀门类型选择电动执行器阀门的种类相当多，工作原理也不太一样，一般以转动阀板角度、升降阀板等方式来实现启闭控制，当与电动执行器配套时首先应根据阀门的类型选择电动执行器。
1．角行程电动执行器（转角<360度）电动执行器输出轴的转动小于一周，即小于360度，通常为90度就实现阀门的启闭过程控制。
此类电动执行器根据安装接口方式的不同又分为直连式、底座曲柄式两种。
a)直连式：是指电动执行器输出轴与阀杆直连安装的形式。
b)底座曲柄式：是指输出轴通过曲柄与阀杆连接的形式。
此类电动执行器适用于蝶阀、球阀、旋塞阀等。
2．多回转电动执行器（转角>360度）电动执行器输出轴的转动大于一周，即大于360度，一般需多圈才能实现阀门的启闭过程控制。
此类电动执行器适用于闸阀、截止阀等。
3．直行程（直线运动）电动执行器输出轴的运动为直线运动式，不是转动形式。
此类电动执行器适用于单座调节阀、双座调节阀等。
二、根据生产工艺控制要求确定电动执行器的控制模式电动执行器的控制模式一般分为开关型（开环控制）和调节型（闭环控制）两大类。
1．开关型（开环控制）开关型电动执行器一般实现对阀门的开或关控制，阀门要么处于全开位置，要么处于全关位置，此类阀门不需对介质流量进行精确控制。
