Instrumentation for electrical vehicle model on road slope using structural analysis

This paper focuses on the design of instrumentation of the control system for electrical vehicle model. The method is based on a structural model that describes qualitatively the different relations of the physical variables. The motivation for the choice of structural analysis approach is that this analysis uses a poor knowledge of the system; it uses only the relation between constraints and variables. By analyzing this model, we obtain the different ways to control the unknown variables in function of the sensors measurements and thanks to the available actuators. The main contributions of this paper combines the merits of: i) the modified structural analysis model in order to take into account different operating cases slope of the road constant and variable and their specific features; ii) to study reject disturbance using graph techniques; iii) to obtain the optimal instrumentation for the system of electrical vehicle which insure controllability in despite of the disturbance.
