机械位移量的自动控制是最常见的控制方式之一,它被广泛地应用于各种对象。在冶金企业中,常见的位移量控制,有各种轧机的压下控制、各种剪切控制以及其它位移装置的准确停车等。对于位移量的控制,通常采用在一定条件下的最佳控制。最常使用的最佳控制方式之一,是要求在最短时间内完成一定的位移量。在这类控制对象中,执行器的速度与被控制的位移量之间形成开方关系。因此,在这种最佳控制系统中,需要设置一个开方器。下面简述一下,为什么在这种最佳控制系统中需用一个开方器以及如何确定开方器的特性。 Automatic control of mechanical displacement is one of the most common control methods, it is widely used in a variety of objects. In metallurgical enterprises, the common displacement control, a variety of rolling mill control, a variety of shear control and other accurate displacement of the parking device. For the displacement control, usually under the best conditions under certain control. One of the most commonly used best controls is to require a certain amount of displacement in the shortest amount of time. In this type of control object, the relationship between the speed of the actuator and the amount of displacement to be controlled forms an open relationship. Therefore, in this optimal control system, you need to set up an opener. Here’s a brief explanation of why an extractor is needed in this optimal control system and how to determine the characteristics of an opener.
