In order to solve the poor dynamic characteristics and adjustment effect of traditional voltage filter control system of welding machine. In this paper, the mathematical model of the voltage filter control system of welding machine is established, and the fuzzy control rule is applied to the Voltage Control System, and two improved fuzzy control schemes including fuzzy-PID compound control and fuzzy...
Two-phase flow measurement plays an increasingly important role in the real-time, on-line control of industrial processes including fault detection and system malfunction. Many experimental and theoretical researches have done in the field of tomography image reconstruction. However, the reconstruction process cost quite long time so that there are number of challenges in the real applications. An...
A numerical model of the coupled thermal — hydrologic in production and injection of multi-wells of water source heat pump was built by TOUGH software. We analyzed some influencing factors of bringing out thermal breakthrough, which include pumping flux, the distance between multi-wells, the osmosis ratio and groundwater flow velocity on the numerical experiments. The temperature of aquifer relative...
With the applications of predictive control in the process control, the research of algorithm and theory about the predictive control has also achieved great development. Dynamic Matrix Control (DMC) algorithm is a prediction-control algorithm based on the objectpsilas step response. It is suitable for the control systems which are complicate and difficult to build accurate mathematical models. This...
