利用差分进化法对一阶和二阶非线性船舶操纵KT方程中的参数进行辨识,采用积分的方法处理试验数据以获得辨识所需的样本,将辨识结果与前人的方法进行比较,证明该方法能有效提高辨识精度.另外,辨识过程采用平行处理法代替分步辨识法,解决了辨识中的参数相消现象,同时也简化了辨识流程.%Identified the parameters of the first and second order ship maneuvering nolinear response equation.Iteg-rated the test datas to get sample datas. It has been confirmed that this method can improve the accuracy of identification compared to other methods. Using the parallel processing method, instead of step-by-step identification to reduce parameters offset. This method can also simplify identification flow.
