基于MMAS-PID 的板形板厚综合控制

针对带钢冷连轧板形、板厚存在的强耦合关系，建立了板形板厚耦合模型，进行了厚度波动前馈补偿，设计了对角形板形板厚解耦控制系统，实现了板形板厚解耦。同时设计了最大最小蚁群算法（MMAS）优化的PID控制器,对综合控制系统进行了PID参数优化.仿真实现了快速优化PID以满足控制要求,与传统的PID控制相比，MMAS-PID综合解耦控制系统有效提高了板形板厚控制精度.

Shape and Gauge Complex Control with MMAS-PID

In view of interacting each other intensively of shape and gauge in tandem cold rolling process, a shape and gauge coupling model was established, a gauge feedforward compensation system was designed, complex decoupling control system was developed by diagonal decoupling control, and shape and gauge decoupling was realized. Then a PID control system with MMAS was designed and improved parameters of PID control system. The simulations realized optimized PID quickly for satisfying demands of controlling, compared with tradition PID, the MMAS-PID complex decoupling control system improved effectively the precision of shape and gauge.
