摘　　要：随着设计系统结构的日益复杂,选择合理的设计方法与结构已成为软件设计中的关键技术。目前,在软件设计领域,有限状态机(FSM)的理论俨然已自成一体,经常用来描述一些复杂的算法,表明算法内部的状态结构,关注对象的执行顺序等。据此,本文以EDA和PLC这两种不同的支持平台为载体,对有限状态机方法的结构体系及应用进行研究。结果表明,FSM方法将控制过程分成有限个稳定状态,描述对象所经历的状态序列与转移,从而解决电子领域中诸多控制问题。且在不同的应用平台上,FSM方法的核心要素不变。With the increasing complexity of designed system structure, selecting suitable design method and structure has be- come the essential technology in software design. So far, the theory of finite state machine （FSM） has been well developed in the soft-ware design domain. It is commonly used to describe some complex algorithms, to illustrate the internal state structure of the al- gorithm, and to follow the execution sequence of the object. Accordingly, based on EDA and PLC platforms, this paper studies the structural system and application of the method of finite state machine. It is indicated from the results that the method of finite state machine divides the controlling process into finite stable states, describes the state sequence and transition of the object, and there- fore solves diversified controlling problems in electronic area. It should be pointed out that essential factors of the method of FSM re- main in different application platforms.
