In this paper, an efficient control system development method based on real-time virtual hardware-in-the-loop simulation is presented. Instead of developing and testing control system after physical prototype is produced, it can be conducted immediately after concept of controlled system is designed by developing a pure software real-time simulator. In this simulator, all the hardware is virtual. The appearance and operation of these virtual hardware is programmed to imitate corresponding physical prototypes so as to implement real-time virtual hardware-in-the-loop simulation. So The control software and the control logic of control system can be developed quickly. And the source code is compatible with both the simulation platform and physical platform. Moreover, It's much easier and faster to debug and test the control logic in such a way. An example of a large and high-groove density ruling engine is provided to explain detail implementation of the proposed method.

Validating that software components meet their requirements under a particular deployment scenario is very challenging. We describe a new approach that uses component aspects, describing functional and nonfunctional cross-cutting concerns impacting components, to perform automated deployed component validation. Aspect information associated with J2EE component implementations is inspected after component deployment by validation agents. These agents run automated tests to determine if the deployed components meet their aspect-described requirements. We describe the way component aspects are encoded, the automated agent-based testing process we employ, and our validation agent architecture and implementation.
