电气操控原理电路规划的办法主要有剖析规划法和逻辑规划法两种。

1、剖析规划法

剖析规划法是依据出产工艺的要求挑选适当的基本操控环节（单元电路）或将比较成熟的电路按其联锁条件组合起来，并经弥补和修改，将其综合成满意操控要求的完好线路。当没有现成的典型环节时，可依据操控要求边剖析边规划。

剖析规划法的优点是规划办法简单，无固定的规划程序，它是在熟练掌握各种电气操控电路的基本环节和具有必定的阅览剖析电气操控电路能力的基础进行的，简单为初学者所掌握，关于具有必定作业经验的电气技术人员来说，能较快地完结规划任务，因此在电气规划中被遍及选用；其缺点是规划出的方案不必定是最佳方案，当经验不足或考虑不周全时会影响线路作业的可靠性。为此，应反复审核电路作业情况，有条件时还应进行模仿试验，发现问题及时修改，直到电路动作准确无误，满意出产工艺要求为止。

2、逻辑规划法

逻辑规划法是使用逻辑代数来进行电路规划，从出产机械的拖动要求和工艺要求出发，将操控电路中的接触器、继电器线圈的通电与断电，触点的闭合与断开，主令电器的接通与断开看成逻辑变量，依据操控要求将它们之间的关系用逻辑关系式来表达，然后再化简，做出相应的电路图。

逻辑规划法的优点是能获得理想、经济的方案，但这种办法规划难度较大，整个规划过程较杂乱，还要涉及一些新概念，因此，在一般常规规划中，很少单独选用。其具体规划过程可参阅专门论述材料，这儿不再作进一步介绍。
