解析机电电子控制技术的发展概况 现代科学技术的发展极大地推动了机械工业领域的变革，同时给相关生产产业带来了巨大的影响，提高了生产水平和技术。随着各种技术之间相融合的发展，以计算机电子技术、机械技术为核心的机电控制领域将给工业及科研等领域带来更多的实际应用。 The development of modern science and technology has greatly promoted the changes in the field of mechanical industry, at the same time to the relevant production industry has brought the huge influence, improve the level of production and technology. With the development of various kinds of technology integration, electromechanical control field in computer and electronic technology, mechanical technology as the core will bring more practical applications for Industry and scientific research field. 　　 　　1.1 计算机控制理论的形成与技术的发展 The formation and development of the technology of computer control theory 1.1 　　忽略数字信号的量化效应，可以将计算机控制系统看成采样控制系统，在这一系统中，将其中连续的环节离散化，则整个系统又可看成由不同的离散系统构成。计算机控制理论的发展主要是将采样理论、差分方程、变换理论、状态空间理论和系统辨识自适应控制等理论综合应用到控制技术中，使计算机控制系统有了初步发展。对于结构复杂、时变的非线性系统，控制系统则融入了鲁棒控制、模糊控制、预测控制等多种新型理论，逐步形成了工业过程控制系统的一个新方向。 Ignore the quantization effect of the digital signal, the computer control system as the sampling control system, in this system, which will be a continuous link discretization, the whole system can be regarded as composed of discrete systems with different. Development of computer control theory is mainly the sampling theory, differential equation, transform theory, the state space theory and system identification, adaptive control and comprehensive application of theory to control technology, the computer control system to have the preliminary development. For the nonlinear system with complicated structure, time-varying, control system is integrated into a variety of robust control, fuzzy control, predictive control and model theory, and gradually formed a new direction of the industrial process control system. 　　自世界第一台电子计算机问世后，计算机首先被用来自动检测化工生产过程的过程参量并进行相关的数据处理，同时也研究了计算机的开环控制。到二十世纪六十年代，出现了用于过程控制的计算机，实现了直接数字控制。后经集中式计算机控制系统发展到现在的以微处理器为核心的分层式控制系统控制，通过计算机对生产过程进行集中监视、操作和管理控制等。伴随着计算机处理器等技术的发展，计算机控制技术也随之发生相应的变革，最终应用到工业生产中并对其产生巨大影响
