Description

technical field [0001] The invention belongs to the field of crystallizers, in particular to an automatic control system for crystallizers in potash fertilizer production. Background technique [0002] Automatic control refers to the use of external equipment or devices to make a certain working state or parameter of a machine, equipment or production process automatically operate according to a predetermined rule without direct participation of humans. Automatic control is relative to the concept of manual control. [0003] The research of automatic control technology is beneficial to liberate human beings from complicated, dangerous and cumbersome working environment and greatly improve the control efficiency. Automatic control is a branch of engineering science. It involves the automatic influence on a dynamical system using the principle of feedback so that the output value is close to our desired value. [0004] The crystallizer process is one of the core processes i...
