借助系统的模型对系统加以研究,是人类研究自然界的科学方法之一。最初,人们对生产的简单工具通过实践了解其性能。随着科学技术的不断发展,产品越来越复杂,价格越来越昂贵,用对实物进行检验的办法不但耗资巨大,也延长了产品研制的周期。像飞机、火箭这样大型的精密产品,为了对它们各方面的性能作一全面的检验和评估,就不得不借助于仿真。在系统工程和控制工程领域中,有各种各样的系统作为研究对象,诸如电气、电子电路、飞行器、工业装置和经济系统等,统称为实际系统。当研究实际系统的预测、控制、规划、
It is one of the scientific methods for mankind to study nature by using system model to study the system. Initially, people understood the performance of simple tools for production through practice. With the continuous development of science and technology, products become more and more complex, the price is more and more expensive, and the method of testing the physical objects is not only costly but also prolongs the period of product development. Large precision products such as airplanes and rockets have had to resort to simulation in order to conduct a comprehensive inspection and evaluation of their performance in all aspects. In the field of systems engineering and control engineering, there are a variety of systems to study, such as electrical and electronic circuits, aircraft, industrial installations and economic systems, collectively referred to as actual systems. When studying the actual system of forecasting, control, planning,
