加热炉温度串级控制系统设计

加热炉温度串级控制系统设计摘要：温度控制系统广泛应用于工业控制领域，如钢铁厂、化工厂、火电厂等锅炉的温度控制系统，电焊机的温度控制系统等。加热炉温度控制在许多领域中得到广泛的应用。生产自动控制过程中 ,随着工艺要求 ,安全、经济生产不断提高的情况下 ,简单、常规的控制已不能适应现代化生产。传统的单回路控制系统很难使系统完全抗干扰。串级控制系统具备较好的抗干扰能力、快速性、适应性和控制质量，因此在复杂的过程控制工业中得到了广泛的应用．对串级控制系统的特点和主副回路设计进行了详述，设计了加热炉串级控制系统，并将基于 MATLAB 的增量式 PID 算法应用在控制系统中。结合基于计算机控制的 PID 参数整定方法实现串级控制，控制结果表明系统具有优良的控制精度和稳定性。关键词：干扰串级控制主回路副回路Abstract: Automatic control of production process, with the technical requirements,security, economic production rising cases, simple, conventional control can not meetthe modern production. The traditional single-loop control system is difficult to makethe system completely anti-interference. Cascade control system with goodanti-jamming capability, rapidity, flexibility and quality control, and therefore acomplex process control industry has been widely used. Cascade control system of thecharacteristics and the main and sub-loop design was elaborate, designed cascadecontrol system, furnace, and MATLAB-based incremental PID algorithm is applied inthe control system. Combination of computer-based control method to achieve PIDparameter tuning cascade control, control results show that the system has excellentcontrol accuracy and stabilityKeywords: Cascade control, interference, the main circuit, the Deputy loop目录1.前言..............................................................................................................................................32、整体方案设计.............................................................................................................
