PLC技术在工业自动化、物联网控制等领域的应用

以目前来看，PLC技术广泛应用于工业自动化、汽车电子、交通运输、物联网控制等各个行业，它在这些领域的作用大致可分为四大类。

一、用于实现各种运动控制

PLC控制器是一种具有微处理机的数字电子设备，用于自动化控制的数字逻辑控制器，可以将控制指令随时加载内存内储存与执行，可编程控制器由内部CPU，指令及资料内存、输入输出单元、电源模组、数字模拟等单元所模组化组合成。PLC控制器可以用于圆周运动或直线运动的控制，如今主要的PLC控制器产品几乎都有运动控制功能，它运用在各种机械、机床、机器人、电梯等场合。

从控制机构配置来说，早期直接用于开关量I/O模块连接位置传感器和执行机构，现在一般使用的运动控制模块，如可驱动步进电机或伺服电机的单轴或多轴位置控制模块。

二、实现工业的过程控制

作为工业控制计算机，PLC控制器能编制各种各样的控制算法程序，完成闭环控制，在工业过程控制中，PLC主要是对温度、压力、流量等模拟量等参数进行闭环控制。大中型PLC都有PID模块，PID调节是一般闭环控制系统中用得较多的调节方法，目前许多小型PLC控制器也具有此功能模块。

三、实现相关的数据处理

现代的PLC控制器具有数学运算、数据传送转换等功能，可以完成数据的采集、分析及处理；这些数据可以与存储在存储器中的参考值比较，完成一定的控制操作，也可以利用通信功能传送到别的智能装置。在大型的控制系统，如无人控制的柔性制造系统中，PLC控制器是核心部件。

四、PLC通信和物联网
Some manufacturers of integrated gate commutated thyristor IGCT (integrated gate commutated thyristor) are also called GCT (gate commutated thyristor), that is, gate commutated thyristor, which is a new power electronic device emerging in the late 1990s.

The integrated gate commutated thyristor IGCT combines the advantages of IGBT and GTO. Its capacity is equivalent to that of GTO, but its switching speed is 10 times faster than that of GTO. Moreover, it can eliminate the huge and complex buffer circuit of GTO application, but the driving power required is still large. At present, IGCT is in fierce competition with IGBT and other new devices, trying to eventually replace GTO in high-power applications. The industry believes that the high proportion of power electronic devices is one of the two characteristics of the new power system. For example, the internationally leading flexible DC transmission technology in the fields of new energy grid connection, offshore wind power transmission and UHV combines advanced technologies in power electronics, power system, communication principles and so on. Modular multilevel converter, DC circuit breaker and DC transformer d on power electronic technology are the key equipment to build DC power grid. Large capacity semiconductor devices are the core components of these key equipment. Low cost, low loss and high reliability of large capacity semiconductor devices are very important to improve the economy and safety of DC power grid equipment. Among high-power power electronic devices, IGBT (insulated gate bipolar transistor) is mainly used at present, while IGCT (integrated gate to gate commutated thyristor) is a more potential semiconductor device. The market is mainly occupied by foreign enterprises such as abb in Switzerland, Infineon in Germany, Ge in the United States, and there is a wide space for domestic substitution
