回转窑煅烧带温度的控制水平直接影响水泥的质量、产量以及能耗,由于回转窑的生产过程具有大惯性、纯滞后、非线性等特点,难以得到精确的数学模型,常规PID控制算法难以满足其控制要求。探索将模糊PID控制算法引入到回转窑温度控制系统中,以实现较好的控制效果。详细介绍了模糊PID控制器的设计过程,通过仿真试验表明,模糊PID控制器提高了系统抗外部干扰和适应内部参数变化的鲁棒性,保证了回转窑温度控制系统的精度。
Rotary kiln calcination zone temperature control level directly affects the quality of cement, production and energy consumption, due to the rotary kiln production process with large inertia, pure lag, nonlinear characteristics, it is difficult to get accurate mathematical model, conventional PID control algorithm is difficult to meet Its control requirements. Explore the fuzzy PID control algorithm introduced into the rotary kiln temperature control system, in order to achieve better control effect. The design process of the fuzzy PID controller is introduced in detail. Simulation results show that the fuzzy PID controller enhances the robustness of the system against external disturbances and changes of internal parameters, and guarantees the accuracy of the rotary kiln temperature control system.
