Systems engineering and computer-aided cotrol system design methods are playing critical roles in today's automotive control system development process. The increased complexity and tight coupling of powertrain subsystems have rendered the traditional subsystem-oriented development process ineffective in meeting the new challenges faced by the industry. In this paper, the authors delineate a systems engineering-oriented control design process, which takes advantage of the readily available, advanced computer-aided tools and process models. It is shown that optimization and sensitivity analysis can be used effectively to derivate reasonable subsystem requirements from higher (potentially competing) system level requirements. Since these techniques can be carried out using computer-based simulation and system models, design and trade-off analysis can be completed rather quickly at the early stage. Thus, the development time and cost can be reduced.
