摘    要：针对非线性信息处理的特点，提出了一种新的DNA计算模型．该模型以创发性机制为基础，引入合理的元进化算子，并由混沌动力学系统构造相应的演化过程．所设计的与上述模型相联系的混沌进化算法，属于一种新型的DNA算法．从将其应用于Hénon方程辨识的结果来看，所构造的模型和算法是有效的，由于非线性控制系统中混沌现象的存在，它们在自适应控制器的设计和应用中具有重要的科学意义和较为广阔的前景.

Abstract: This paper proposes a new DNA computational model based on the features of nonlinear information processing. This model in which some resonable meta-evolution operators are applied is based on emergent mechanism. The corresponding evolutionary procedure is implemented by chaotic dynamics system. The related chaotic evolutionary algorithm belongs to a new type of DNA algorithm. According to the application in Hénon equation identification, the model and algorithm are efficient. Owing to the existence of the chaos phenomena in nonlinear control system, they are of scientific significance and practical perspects for adaptive controller designing and application.
