中文摘要：

针对差分进化算法全局寻优效率偏低的弱点,提出了一种灾变策略,用以改进常规差分进化算法。该策略通过在进化过程中引入尖点灾变模型并适时进行灾变操作。实例测试表明这种灾鞭策略效果良好,并已成功地应用于铯-铷-钒系低温硫酸催化剂上SO2催化氧化反应动力学模型的非线性参数估计。

英文摘要：

To address the low efficiency of the global optimization in the searching process of differential evolution,a differential evolution based on catastrophic strategy （CDE） was proposed,which applied the idea of a cusp catastrophic model and disaster operation timely.In this algorithm,simulation study of CDE shows that the catastrophic strategy to be effective.Finally,the CDE has been successfully applied to nonlinear parameter estimation of the model of low temperature SO 2 oxidation with Cs-Rb-V sulfuric acid catalyst.
