A new method of catastrophe control is described in one dimension nonlinear system. Catastrophe control based on catastrophe theory is a brand new area for control theory. A certain catastrophe is created at a desired location by appropriate control, which has preferred properties. Washout filter is presented and applied to preserve the original equilibrium of a system.Washout filter aided dynamic feedback controller is developed for the creation of eatastrophe, and an example is given to illustrate the process. Catastrophe control may provide a new way of designing warning signals of impending collapse or catastrophe for monitoring and control purposes. 相似文献

经过计算的闸后冲刷深度,经模型试验论证偏大。计算时可考虑闸后冲刷坑再逐步形成,因此闸后水深也再逐步加深,这样计算出来的闸后冲刷深度和模型试验数据较为吻合。 相似文献
