摘　　要：焦炉集气管压力控制系统是炼焦自动化生产过程中的重要组成,该系统具有非线性、时变性和强扰动等特点。传统的常规PID控制已不能满足现场复杂生产工艺的要求。文中设计采用基于最小二乘支持向量机LS_SVM的内模控制器IMC,应用于焦炉集气管压力控制系统,具有调节性能好、鲁棒性强、以及能消除不可测干扰等优点。仿真结果表明,该控制器具有较简单的模型和良好的控制性能。Coke oven collector pressure control system is an important part in the process of coking production. The system has the characteristics of nonlinear,time varying and strong disturbance. The conventional PID control cannot meet the requirements of the complex production process. The design used the internal model controller based on least squares support vector machines. The controller which is applied to coke oven gas collector pressure control system has the advantages of good performance,strong robustness,and can eliminate the interference. The simulation results show that the controller has a simple model and a good control performance.
