根据电渣重熔过程的工艺特点和数学模型,提出了基于改进混合蛙跳算法(ISFLA)的多变量参数自整定PID控制策略.提出一种新的蛙跳规则,用以增强SFLA的局部搜索能力.该规则主要通过模拟青蛙的感知和运动的不确定性来动态随机地调整青蛙的局部搜索空间和步长,以防止SFLA算法过早收敛,提高算法的搜索效率.仿真结果和工业应用实验均表明了所提出控制方法的可行性和有效性. According to the process characteristics and mathematical model of ESR process, a multivariable parameter self-tuning PID control strategy based on the improved hybrid Frog Leaping Algorithm (ISFLA) is proposed. A new frog leap rule is proposed to enhance the local search of SFLA Ability.The algorithm dynamically and randomly adjusts the frog’s local search space and step size by simulating frog’s perception and motion uncertainty to prevent premature convergence of SFLA algorithm and improve the search efficiency of the algorithm.The simulation results and industrial application experiment Both demonstrate the feasibility and effectiveness of the proposed control method.
