摘要提出了一种用于非线性动态系统辨识的激励信号产生方法。与基于特定信号类型的传统方法相比，这里的目标是模型输入空间中数据点的均匀分布。在整个输入空间中的空间填充数据分布对于收集关于系统的非线性的信息是必要的，并且使外推的风险最小化。该方法可以扩展到多个输入，适度增加复杂性，这是大多数现实世界应用的关键特征。通过仿真和高压燃油供应系统验证了激励信号的质量。
Abstract A methodology to generate excitation signals that can be used for the identification of nonlinear dynamic systems is proposed. In contrast to traditional approaches which are based on specific signal types, the objective here is the homogeneous distribution of the data points in the input space of the model. A space-filling data distribution in the whole input space is a necessity for gathering information about the nonlinearities of the system and minimizes the risk of extrapolation. The methodology can be extended to multiple inputs with moderate increase in complexity which is a key feature for most real-world applications. The quality of the excitation signal is demonstrated with simulations and on a high pressure fuel supply system.
