| Abstract: | This paper analyzes the positional and the incremental algorithm based on the PID control, which is widely used in the industrial automation field. With the Siemens S7 -300 PLC as a controller, the PID common control algorithm is realized in the way of ladder and packaged it in a function block. By selecting the appropriate PID parameters, it can be used in kinds of practical engineering programs. The control algorithm has been successfully applied in the actual processing project and subway ventilation air conditioning project. |
