摘要
论文建立余热锅炉汽包水位的数学模型,对该数学模型进行分析和验证,并对余热锅炉汽包水位动静态特性进行分析。在讨论了汽包水位在单冲量和三冲量方式下的常规PID控制器和自整定控制方案后,重点研究一种基于模糊控制的自整定PID控制对水位参数进行实时调整。针对该控制策略,应用Matlab/Simulink进行仿真分析,仿真研究表明,这种方案使汽包水位控制系统具有较强的鲁棒性及良好的控制品质,提高了系统的动静态性能指标。
This paper builds the model of the drum water level of a heat recovery steam boiler, analyzes the dynamic and static characteristics of it. After introducing the projects of normal PID control using on single/three momentum and self - tuning controller, this paper analyzes the method of a fuzzy self - tuning PID controller which is used on the water level of a boiler. Aiming at the method, this paper I use Matlab/Simulink to simulate the result. The MATLAB simulation results show that the scheme provides the control system the stronger robustness and better control quality, and improves its dynamic and static performance index.
