摘要
利用非线性系统多个工作点上的线性化模型,建立了一类参数内插型多模态ARMAX模型。与传统的线性化模型相比较,在较大的工作范围内有较高的精度。根据多模态模型设计的控制器,由于能够综合利用非线性系统多个工作点上的静态与动态信息,所以具有良好的性能。仿真例子表明多模态模型的有效性。
A multiple mode ARMAX model with its parameters interpolated is developed by using linearized models at several operating points of the nonlinear system. Such n a model is more accurate in a larger working extent than the traditional linear model, and the controller designed based on it is of good perfermance because it enables us to use the information of the nonlinear system at several operating points. Simulation results have demonstrated its effectiveness.
