Decoupling Control Research of the Strip-Cast Looper Height and Tension QDRNN Network

Abstract:

Based on the classical cast theory and modern hot continuous rolling theory, in order to improve further the thickness precision of casting and control quality, so the dynamic mathematical model of strip-cast Looper system was established, which is nonlinear, strong coupling and uncertainty. According to the actual data, the comparative complete transfer function of Looper system is calculated. And the QDRNN-PID control strategy is put forward to subtract the coupling effect of Looper system. The simulation results prove that this control strategy can obtain a better control effect of Looper system after decoupling.
