自动控制可分成断续控制和连续控制。断续控制即开关控制。气动控制系统中使用动作频率较低的开关式(ON-OFF)的换向阀来控制气路的通断。靠减压阀来调节所需要的压力，靠节流阀来调节所需要的流量。这种传统的气动控制系统要想要有多个输出力和多个运动速度，就需要多个减压阀、节流阀及换向阀。这样，不仅元件需要多，成本高，构成系统复杂，且许多元件都需要预先进行人工调节。电气比例阀控制属于连续控制，其特点是输出量随输入量的变化而变化，输出量与输入量之间存在一定的比例关系。比例控制有开环控制和闭环控制之分。

典型的伺服阀由永磁力矩马达、喷嘴、档板、阀芯、阀套和控制腔组成(见图)。当输入线圈通入电流伺服阀时，档板向右移动，使右边喷嘴的节流作用加强，流量减少，右侧背压上升；同时使左边喷嘴节流作用减小，流量增加，左侧背压下降。阀芯两端的作用力失去平衡, 阀芯遂向左移动。高压油从S流向C2，送到负载。负载回油通过 C1流过回油口，进入油箱。阀芯的位移量与力矩马达的输入电流成正比，作用在阀芯上的液压力与弹簧力相平衡，因此在平衡状态下力矩马达的差动电流与阀芯的位移成正比。如果输入的电流反向，则流量也反向。表中是伺服阀的分类。
