Design of Functional Interval Observers for a Battery and Motor Circuit Model of Electric Vehicle

In this paper we first establish a model of battery and motor circuit for electric vehicle (EV). We then consider the problem of estimating linear functions of the state vector of this model. We design two novel observers to estimate the set of admissible values for linear functions of the state vector at each instant of time. Conditions for the existence of the linear functional interval observers are given and an effective algorithm for computing unknown observer matrices is presented.
