Control system of the boiler water level based on normalized PID

The Control system of the industry boiler water level is designed. The control algorithm used normalized PID control algorithm based traditional PID. A normalized parameter setting method is introduced for adjustment of PID parameters. The boiler water level control system is designed based on the Kingview software development platform. The main controller is realized with PLC. The configuration software is used to configure hardware and network. The experimental results prove that the combination of the PLC control system and Kingview configuration software is valuable for design, testing and application.
