功率放大器：

逐渐加大输入信号，使阀芯开始移动，但由于阀口遮盖量过大，阀出口并无流量输出，只有当阀口开度约为大开度的25%时，阀出口才有流量输出。

当输入信号达到或超过大输入信号的25%时，阀出口才有流量输出，其大小取决于阀的开度。

当无控制信号时，过大的阀口遮盖量会使泄漏减少，但从控制角度来说，并不希望有太大的死区。

死区补偿

不过，通过调整功率放大器上的死区补偿电位计，可以减小死区。

首先将输入信号的1% ( 0.1V )定为死区，并保持之。

不过，当输入信号超过这个阀值时功率放大器输出就会跳过该阀值，以将阀芯移动至死区边缘。此时将产生与输入信号0.1-0.2 V相对应的流量，然后，阀口将随着输入信号的增加而逐渐开启。然而，当输入信号约为7.5V时，阀口开度将大。实际上，从阀芯开始移动至停止，死区也在移动。

比例控制技术是在开关控制技术和伺服控制技术之间的过渡技术，采用比例放大器控制比例电磁铁，实现对比例阀的连续控制，从而实现对液压系统压力、流量、方向的无级调节；但是用比例方向阀进行速度控制时，如果负载是变化的，那么执行元件的速度就会受负载变化的影响（负载小时速度快，负载大时速度慢）；于是在系统设计时，人们引入了压力补偿器，它可以使比例阀阀口的压差保持恒定，使执行元件的速度不受负载变化的影响。

光纤放大器一般都由增益介质、泵浦光和输入输出耦合结构组成。目前光纤放大器主要有掺铒光纤放大器、半导体光放大器和光纤拉曼放大器三种，根据其在光纤网络中的应用，光纤放大器主要有三种不同的用途：在发射机侧用作功率放大器以提高发射机的功率；在接收机之前作光预放大器以较大地提高光接收机的灵敏度；在光纤传输线路中作中继放大器以补偿光纤传输损耗，延长传输距离。
