Development Of Embedded System And Application In Motor Control

With the rapid extension of computer application domain, and the continuous increase of software scale and complexity, the software crisis is exposed more obvious, the most important thing is increasing software productivity of software industry. Software reuse is the important domain of software engineering. It is the main route to solve software crisis and enhance software productivity, quality, opening and the adaptability for the out disturbance. At present, the research about software reuse focuses on the software based on component, it's considered as one of the key factors of realizing succeeding in software reuse. The reused resources include not only programs but also the methods, requirement specification, design construction, development tools and environment, testing and analysis data and maintain information, etc. The reusable resources are called component, component is the foundation of software reuse. The development Technology based on the component can construct a new application rapidly by reusing the component available or developing a little new components as the computer hardware engineers constructing a new computer with the IC. The software reuse technology of embedded system based on component is the key content in this text. The article introduced the hardware foundation of the embedded system and basic theories, and the current researching situation and development prospect of domestic and international. The software system structure model, the step of programming used the component, assembly language and component-base of Micro Message Bus (MMB) were discussed in detail. The development tools and environmentdesigned for software reuse -MMB Integrated Development Environment isanother content of this paper. As an application instance, the direct torque of asynchronous motor control explained the development course of the actual project using the component technology. MMB applies employs the software component technology, easily expanded, conveniently reused and simply applied, and has very high social value and economic benefits.
