The heat exchange of distilled water unit is a very complex process.The main steam pressure and temperature are tightly coupled with the pressure of raw water, temperature and flow in the circuit, and show non-linear relationship. There are two important parameters need to be controlled in water production process: conductivity and temperature of distilled water at the exit. This is a typical double...
In order to improve tracking accuracy of the servo system, an adaptive inverse controller with PID feedforward is designed. It is based on the time-delay characteristic of the adaptive inverse control when training. The controller can realize accurately tracking of the servo, so as to meet the working need of the system. Finally, the tracking simulation is carried out on the digital servo experimental...
The FPGA image preprocessing system architecture which uses Sobel algorithm to realize the adaptive edge detection is proposed, and the image data stream read, pre-storage, pretreatment and post-buffering can be achieved in the system. The high-speed stream storage system with complete data flow control path and flexible small-core processing technology is adopted in the design for the realization...
As the visits to databases in the network application become more and more, the DBMS, which is the core of network calculation, attracts increasing attention. The research on the self-calculating, which mainly includes self-configuring, self-restoring, self-optimizing and self-protecting, handles the internal resources management of the DBMS. But it can't handle the management of external workload...
Inherent pH process nonlinearity and time-varying characteristics impose a highly challenging control problem. This paper presents an incorporation of offline process model identification and a QFT control methodology to develop a robust control scheme for a pH neutralization process plant on the basis of SISO QFT bounds. The obtained simulation results indicate the efficiency of the proposed control...
The typical coupled-tanks process that is TITO plant has the difficulty in controller design because changing of system dynamics and interacting of process. This paper presents design methodology of auto-adjustable PI controller using MRAC technique. The proposed method can adjust the controller parameters in response to changes in plant and disturbance real time by referring to the reference model...
A Reinforcement Learning (RL) method called SARSA is used to dynamically tune a PI-controller for a Continuous Stirred Tank Heater (CSTH) experimental setup. In order to start from an acceptable policy, the proposed approach uses an approximate First Order Plus Time Delay (FOPTD) model to train the RL agent in the simulation environment before implementation on the real plant. As a result of the existing...
