摘　　要：机械控制工程基础在大学课程体系当中占有重要的地位,其理论的补充与完善具有重要的工程应用价值。针对已经普遍存在而确实不妥的概念进行创新性改进。基于等效代换原则,实现了相加点与分支点互换,补充了两者不能直接互换的知识点;基于时代特征,将古典控制论和现代控制论分别规范化为简单系统和复杂系统控制理论;澄清了闭环和开环的定义;根据定义,将最大超调量和稳定裕度分别规范化为最大超调比和稳定裕量;分析了Nyquist图和Bode图的编排顺序,可按照两条思路理解等。这些创新点使该学科更便于学习和研究。The mechanical control engineering foundation plays an important role in the university curriculum system. The supplement and perfection of this theory has important engineering application value. Several inappropriate universal concepts are improved. Based on the principle of equivalent substitution, the phase point and branch point position are exchanged. The knowledge point that the two can＇t be directly interchanged is added. Based on the times characteristics, the classical control theory and modern control theory are standardized for simple system and complex system control theory. The definition of closed loop and open loop is clarified. According to the definition, the maximum overshoot and stability margin degree are normalized to the maximum ratio and the stability margin. The order of the arrangement of Nyquist and Bode is analyzed. It can be understood in accordance with two ideas. These innovations make it easier to learn and study.
