Abstract

In order to compete in the global market, engineering organizations are under increasing pressure to design, develop, and deploy products in the market place as quickly as possible with first time quality. In order to achieve these objectives, it is necessary to streamline the design and development process, namely, “transfer of analytical design of Intelligence to Mechatronics intelligence” in an efficient and expedient manner. An increasing pressure exists on the development cycle of control systems to serve this widening application spectrum. The time-to-market of a new product often determines its commercial success. Consequently, design problems have to be discovered as early as possible in the design process in order to take remedial actions. Efficient and accurate tools and procedures are required to support short yet successful development processes. Over the last two decades, commercially available computer has become both increasingly powerful and increasingly affordable. This, in turn, has led to the emergence of highly sophisticated simulation software applications that not only enable high-fidelity simulation of dynamic systems and related controls, but also automatic code generation for implementation in industrial controllers. Simulation tools have been widely used for the design and improvement of electrical systems since the mid twentieth century. The evolution of simulation tools has progressed in step with the evolution of computing technologies. In last ten years, computing technologies have improved dramatically in performance and become widely available at a steadily decreasing cost. Consequently, simulation tools have also seen dramatic performance gains and steady cost decreases. Researchers and engineers now have access to affordable, high-performance simulation tools that were previously too cost prohibitive, except for the largest manufacturers and utilities. The purpose of this paper is to review major milestones that set the stage for the development of the today's real time simulation including sufficient detail to acquaint reader with their basic principles, strength, challenges and its applications.
实时仿真:最近的进展和挑战
为了在全球市场上竞争,工程组织承受着越来越大的压力,以尽可能快的质量设计、开发和部署市场上的产品。为了实现这些目标,必须简化设计和开发过程,即以高效和方便的方式“将智能分析设计转换为机电一体化智能”。控制系统的开发周期面临越来越大的压力,以满足日益扩大的应用范围。新产品的上市时间往往决定了它在商业上的成功。因此,必须在设计过程中尽早发现设计问题,以便采取补救措施。需要有效和准确的工具和程序来支持短期但成功的开发过程。在过去的二十年里,商用计算机变得越来越强大,价格也越来越便宜。这反过来又导致了高度复杂的仿真软件应用程序的出现,这些应用程序不仅可以实现动态系统和相关控制的高保真仿真,而且还可以在工业控制器中实现自动代码生成。自二十世纪中期以来,仿真工具已广泛用于电气系统的设计和改进。仿真工具的发展与计算技术的发展是同步的。在过去的十年中,计算技术在性能上有了显著的提高,并以稳步下降的成本得到了广泛的应用。因此,模拟工具的性能也得到了显著提升,成本也稳步下降。除了大型制造商和公用事业公司之外,研究人员和工程师现在可以使用价格合理的高性能仿真工具,这些工具以前成本过高。本文的目的是回顾为当今实时仿真发展奠定基础的主要里程碑,包括足够的细节,以使读者熟悉它们的基本原理,强度,挑战及其应用。
