In this paper, the emergency braking of high speed train is studied, and the relationship between the braking force, resistance, speed and deceleration is discussed. According to the Newton's second law of motion, by discretizing the speed and displacement, the emergency braking model of high speed train is established. Further, the unobserved braking parameters of model are identified by the iterative...
In this paper, a method for a sort of nonlinear system identification with stochastic time-varying parameter is investigated. This kind of nonlinear systems is referring to the system where probability density functions (PDFs) of the parameters are known. This parameter identification and states estimation method is realized based on expectation maximization (EM) algorithm and particle filter. Firstly,...
