针对轧钢加热炉炉膛燃烧工况复杂、各区段温度响应存在滞后性和参数耦合性等问题，提出一种基于改进烟花算法(improved fireworks algorithm，IFWA)优化的延时输出滑模控制(delayed output sliding mode control，DOSMC)加热炉耦合燃烧系统控制策略，以加热炉各区燃料量为控制量、各区炉膛温度为被控量，构建三区炉温耦合模型，利用伴随矩阵解耦方法对模型进行解耦，设计基于改进烟花算法优化的滑模控制器，构造延时输出观测器估计系统的延时输出并补偿。研究结果表明:与IFWA-DOSMC控制、DOSMC控制和PID控制相比，提出的解耦IFWA-DOSMC控制系统有效抑制了时滞和系统耦合对控制效果的影响并且抗干扰能力强，解耦IFWA-DOSMC控制系统无超调，调节时间最短为388。42 s，在系统受到外界干扰时，超调量为11。79%，调节时间为331。59 s;相比于工业现场原控制策略，提出的控制策略控制精度提高了49%，温度偏差范围在±11℃之内，符合现场实际要求。
Heating furnace combustion system control strategy based on time-delay sliding mode optimized by fireworks algorithm
To address the complexity of combustion conditions,as well as the hysteresis and parameter coupling in the temperature response of each section of the heating furnace,a control strategy for the coupled combustion system based on an improved fireworks algorithm(IFWA)-optimized delayed output sliding mode control(DOSMC)was proposed.The manipulated variable was the fuel quantity in each section,and the controlled variable was the furnace temperature.A three-zone coupled furnace temperature model was constructed and decoupled using the adjoint matrix method.An SMC controller optimized by IFWA was designed for the decoupled model,and a delayed output observer was introduced to estimate and compensate for the system's delayed outputs.The results show that,compared to IFWA-DOSMC,DOSMC,and PID control methods,the proposed decoupled IFWA-DOSMC control system effectively suppresses the impact of time delay and system coupling on control performance while exhibiting strong disturbance rejection capabilities.The decoupled IFWA-DOSMC system achieves zero overshoot,with a minimum settling time of 388.42 s,and experiences an overshoot of 11.79%with a settling time of 331.59 s when subjected to external disturbances.Compared to the original industrial control strategy,the proposed approach improves control accuracy by 49%,keeping temperature deviations within±11℃,which meets the practical field requirements.
