Maritime Protection Steam Boiler Systems

Marine steam boiler is an important industrial and civilian and military equipment, It is very extensive. Therefore, the protection of the wind pressure boiler system controller to improve, not only in academic research value, but with significant economic and social benefits.This paper combines engineering. The study focused on the protection of marine steam boiler control device pilot study mathematical modeling and analysis. By analyzing and comparing then showed improved the advantages of the new system. Its main contents are as follows :First, the protection of marine steam boiler controller mathematical analysis and experimental research. Some of the main elements of this in two parts : One is the protection of structures controller mathematical model to the back sections of their mathematical simulation lay a foundation; The second part is to set up a test bed, Simulation control devices to protect the actual working conditions. Then the control device for the protection of undertaking a pilot study. Data acquisition cards for data acquisition, control devices to protect the dynamic characteristics test analysis. Finally, the PC software program for Delphi data real-time detection and handling,then to protect the dynamic characteristics of analysis, its characteristic curve;Secondly, the protection of boiler controller system improvements. Part of this is the core of the entire paper, Its design is to use a pneumatic servo system to replace the original pure mechanical devices to protect the boiler control device. Specifically through the use of a pneumatic servo valve and pressure sensors to several design of a pneumatic servo system to replace the protection of control equipment Boiler home in the role, and through mathematical modeling to analyze the improved pneumatic servo system. After eventually will improve the protection of the control system simulation curve simulation and the protection of the control device simulation curves contrast, and demonstrated its improved superiority. In addition, the control component has been improved. In this paper, using the new adaptive fuzzy PID controller to the conventional PID controller. Conventional PID controller is a linear controller, Linear control system can show a good performance. But the strong nonlinear aerodynamic system, as conventional PID control parameters are fixed. Therefore its control weaknesses on the show. Conversely, the improved adaptive fuzzy PID controller with a fuzzy control and the advantages of PID control. Fuzzy control system can PID control parameters according to the three different conditions - line adjustment thereby improving the overall system performance. To prove adaptive fuzzy PID controller advantages, the paper also by mathematical simulation contrast, comparison of the two controllers improved pneumatic servo system of performance.Finally, the use of Siemens PLC to achieve adaptive fuzzy PID design. This control is the benefits PLC and adaptive fuzzy PID control, both to control the use of PLC reliable, flexible, adaptive characteristics, but also greatly enhance the system of intelligent control. Although this section of this paper is not the core, but it is also a bold attempt and innovation.
