During airdrop of heavy load, the aircraft's flight states vary continuous as the load moving back in the cargo hold, and then change suddenly when the load drops out or leave the hold. This process deteriorates the flight quality as the load becomes heavier. Under the backstepping and switch control methods, the flight state holding can be fulfilled under the assumption of unlimited actuation. And...
The main function of hot rolling process control is thickness setting model of finishing mill and mathematical model of plate setting, which is the core of the mathematical model of hot rolling. After setting value to calculate, it will be sent to basic automatic level and carried out by device control functions. This article uses the finishing mill model which includes the rolling force model, the...
The control strategy of self-tuning observer-compensator for time lag systems is discussed, makes it applied to ammonia plant synthesizing section's hydrogen-nitrogen ratio control, which makes a great successes. The qualified rate of hydrogen-nitrogen ratio increased to about 90% from the original 50% or so.
An improved GMDH called GMDH plus model structural optimization is put forward in this paper. The method has been applied to the manufacture of lubricating oil for recognizing the mathematical model of the dewaxing process of benzd-acetone, and the model acquired is consistent with the actual operating data. Based on this model, an optimal deduction is made for locating the optimal operating order...
