A06B-6078-H306#H500应用程序设计过程中，应正确选择能反映生产过程的变化参数作为控制参量进行控制；应正确处理各执行电器、各编程元件之间的互相制约、互相配合的关系，即互锁关系。应用程序的设计方法有多种，常用的设计方法有经验设计法、顺序功能图法等。

1 经验设计法

经验设计法要求设计者具有较丰富的实践经验，掌握较多的典型应用程序的基本环节。根据被控对象对控制系统的要求，凭经验选择基本环节，并把它们有机地组合起来。其设计过程是逐步完善的，一般不易获得佳方案。程序初步设计后，还需反复调试、修改和完善，直至满足被控对象的控制要求。

经验设计法的设计不规范，没有一个普遍的规律可循，具有的试探性和随意性。
