ABSTRACT

Mobile source air pollution has been recognised as a serious concern in modern society. As a percentage of the total air emissions, it has dramatically increased over the past few decades. Various adverse effects have been analysed with exposure to air contaminations. In this paper, a continuous-time dynamic mobile source air pollution (CDMSAP) model to predict and control the emission levels from a total vehicle population is developed. An essential feature of the model is that it represents the continuous dynamics of vehicle population and related emission levels. The vehicle population is structured into different groups (cohorts) on the basis of the attribute “age”. It is assumed that vehicles of the same group have similar physical characteristics and behaviour. Therefore, the model is suitable for large cities, metropolitan areas or regions, where small group characteristics do not affect the aggregate behaviour of the vehicle population. Because of the nature of mobile source air pollution process, the CDMSAP model exhibits positive linear systems (PLS) behaviour. Maintainability is a property of the vehicle population to maintain (preserve) desired emission levels of pollution. In this paper some very recent advances of control theory for positive systems are used to study maintainability property of CDMSAP model.
