采用Volterra级数解的递推算式与方波脉冲函数变换技术对一类非线性动态C/S的数学模型进行辨识,导出了相应的混合模型辨识公式和动态响应的求解方法。根据该法所得到的混合模型,对C/S施行了多重预置模型的故障诊断方法,并给出了辨识仿真和故障诊断实例。
It is presented to identificate the hybrid models of nonlinear systems by using the block-pulse function transform and Volterra series applied to express the solution of nonlinear dynamic system. The identification formulae concerned are derived. A new fault diagnosis method based on multiple preset models which are computed by this method is proposed. Examples of identificated simulation and fault diagnosis are also given.
