The control structure includes two pieces of equipment. The first equipment includes one analog amount input module connected to the sensor and the second equipment includes control module, analog amount output module connected to the executor. The first equipment has one increased prediction control module and one control module with the same parameters as that in the second equipment and the second equipment has also one increased prediction control module the same as that in the first equipment. Universal configuration software is used in configuring the parameter connection of the modules in the first equipment and the second equipment. The present invention reduces the bus network communication load to raise the real-time property and determinacy of bus network in data communication. The present invention also warns the error sampling data, acting as the second sensor to raise the stability of the control system.
