摘　　要：基于经典区间模型预测控制框架,针对非线性约束条件下的多输入多输出系统,设计了基于人工势场的双层结构控制算法。与传统区间预测控制不同,该算法考虑了系统中的多变量饱和问题。该控制策略利用控制裕度结合人工势场的相关原理,有效抑制了区间控制下的变量饱和现象。最后,以重油初馏塔为例进行仿真验证,表明所提算法有效提高了控制系统的性能和稳定性。Based on the classical interval model predictive control(MPC)framework,and aiming at multi-input-output systems under nonlinear constraints,a two-layer structure control algorithm based on the artificial potential field was designed.This algorithm,different from the traditional interval predictive control,has the multi-variable saturation of the system considered and its control strategy has the control margin and the related principle of artificial potential field adopted to effectively suppress variable saturation phenomenon under interval control.Simulating a heavy oil distillation tower shows that,the algorithm proposed effectively improves the performance and stability of the control system.
