Description
Summary:This paper presents a multi-domain modeling strategy of electric power steering (EPS) fed by PMSM drive systems which are widely being applied in automotive application. Automotive control systems are complex systems involving multidisciplinary knowledge. According to the glowing number of advanced electrical components like ESP, the complexity is rapidly increasing. In order to accomplish complex analysis tasks, the system is modularized into components that are modeled by suitable domain descriptions for reflecting specific characteristics. A PMSM and inverter are represented by the interconnection of circuit elements. On the other hand, system mechanism and loads are described by differential or algebraic equations. Finally, the controller which includes PWM generators is represented in their functional forms that describe the behavioral properties. And then, those are integrated as entire EPS model for analyzing system behaviour with interactions between each component. The MATLAB/Simulink, which is a de facto standard tool in control and system engineering, and SimPowerSystems environment are selected as a solution of the accurate and intuitive multi-domain modeling of the PMSM driven EPS at the system level.
