摘要
提出了一种基于改进差分进化算法的驾驶员诱发振荡(PIO)预测评估方法。针对基本差分进化算法收敛慢、易陷入局部最优的问题,提出了基于混沌理论与高斯扰动的改进型差分进化算法。在此基础上,构建了基于改进差分进化算法的PIO预测评估流程与实施步骤,建立了基于速率限制的人机闭环系统模型。实例计算结果表明,该方法克服了传统评估方法的缺陷,可在多参数摄动情况下对PIO进行快速准确的评估。
This paper presents the prediction and evaluation method for pilot induced oscillations （PIO） based on modified differential evolution. For the problem of slow search and premature convergence in the basic differential evolution, a new modified method based on chaos theory and Gaussian disturbance is proposed. And then the process to evaluate the pilot induced oscillations is put forward. The human ma- chine system model based on rate-limit is set up. The results show that the method can be used to achieve satisfied results in parameters perturbation.
