摘要:
在化工生产过程中，为了减少危险的高温设备操作和安全事故的发生，针对余热锅炉水温控制系统的时变性、滞后性等特点，进行了控制系统优化研究。在MATLAB/Simulink平台建模仿真，比较了常规PID控制、模糊自适应PID控制、串级控制效果，发现各控制方案都存在各自的优缺点。为了利用各控制方案的优点同时减弱其缺陷，提出了复合控制方案对系统进行控制，通过调节各控制器权重系数的方法将选中的控制器复合为一个控制器。PID 控制、串级控制、模糊控制、复合控制和S-函数复合控制系统的响应曲线在230 s、300 s、180 s、130 s和106 s达到稳定。S-函数复合控制响应快、无超调、控制精度较高，达到了使控制系统安全稳定的目的，有效提高了克劳斯硫磺回收燃烧炉余热回收效率。
Abstract:
In the process of chemical production, in order to reduce the occurrence of hazardous high-temperature equipment operations and safety accidents, a study on the optimization of the control system for the water temperature of the waste heat boiler is conducted, targeting its characteristics such as time-varying and hysteresis. The effects of conventional PID control, fuzzy adaptive PID control and cascade control are compared by modeling and simulation on MATLAB/Simulink platform. It is found that each control scheme has its own advantages and disadvantages. In order to make use of the advantages of each control scheme and reduce its defects at the same time, a compound control scheme is proposed to control the system, and the selected controller is combined into a controller by adjusting the weight coefficient of each controller. The response curves of PID control, cascade control, fuzzy control, compound control and S-function compound control system were stable at 230s, 300 s, 180 s, 130 s and 106 s. The S-function compound control has the advantages of fast response, no overshoot and high control precision, which makes the control system safe and stable and effectively improves the waste heat recovery efficiency of Claus sulfur recovery combustion furnace.
