摘要
提出了一种将MATLAB实现的先进算法引入控制组态的DCS (distributed control system)优化方法。编写UDP和Modbus/TCP协议通信程序，建立EDPF-NT + DCS与MATLAB之间的双向数据通信。利用MATLAB中的两个定时器对象来保证数据的实时传输。采用DCS提供的通信接口，保证了系统的独立性和可靠性。最后给出了汽包液位模糊pid控制的应用实例，验证了该方法的可行性。
Optimization of power plant DCS control based on data communication
A DCS (distributed control system) optimization approach introducing advanced algorithm realized in MATLAB into the control configuration was proposed. UDP and Modbus/TCP protocol communication program was written to establish two way data communication between the EDPF-NT plus DCS and MATLAB. Two timer objects in MATLAB were used to ensure real-time transmission of the data. Independence and reliability was guaranteed by using communication interface offered by DCS. An applying example of drum level fuzzy-PID control was given to prove the feasibility of this approach.
