| 摘 要： | 钢厂加热炉是一个复杂的受控对象，存在非线性、时变性和纯滞后等问题，造成建模和控制比较困难。加热炉温度的控制主要依赖于对煤气流量的控制，因此，研究一种合理的煤气流量控制方案是提高加热炉控制水平的关键。提出一种改进的模糊PID控制算法，该算法综合PID控制和模糊控制各自的特点，将 PID 控制和模糊控制相结合，并结合加热炉的特点加以改进，具有很强的适应性和抗干扰能力。仿真结果表明，该算法在克服对象的非线性、纯滞后等方面，性能优良，较好的改善了控制质量。

| Abstract: | The furnace of steel plant is a complex controlled object which has the properties of nonlinear, time-varying and delay. Its modeling and control are very difficult. The temperature control of the furnace mainly depends on the control of gas flow. Therefore, the study of a reasonable gas flow control program is the key to increase the level of heating control. In this paper, an improved fuzzy PID control algorithm is proposed, in which, PID control algorithm and fuzzy control algorithm are integrated together, and its characteristics are improved according to feature of furnace. This made the algorithm to has good adaptability and Interference capability. The simulation results show that the improved control algorithm is better than traditional algorithm in overcoming the non-liner, delay of the object and the performance is excellent. |
