Simulation and Optimization of RAWC System Based on PSO

首先建立了带钢锻轧短行程自动控制模型,采用改进PSO算法对带钢宽度控制进行优化,并引入变异算子优化算法的全局性,采用VB6.0进行模块化编程,实现短行程控制曲线的离线仿真,结果显示,PSO算法优化控制曲线后,板坯头部宽度偏差得到优化,有效减少了带钢端部失宽量,基本消除了与带钢中心的宽度偏差,带钢头尾部失宽区域明显减小。

Established a hot strip short stroke automatic control model. An improved PSO algorithm to optimize control of the strip width, and the introduction of mutation operator to optimize the overall algorithm, using VB6.0 modular programming, to achieve short-stroke control offline simulation curves showed, PSO algorithm to optimize the control curve, the head of the slab width deviation has been optimized to effectively reduce the width of the strip ends of the amount of the loss, basically eliminating the strip width deviation from the center of the strip head and tail loss of wide area significantly reduced.
