【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。
[Abstract]:The foundation of mechanical control engineering plays an important role in the university curriculum system, and the supplement and perfection of its theory has important engineering application value. Make innovative improvements to concepts that are already widespread and really inappropriate. Based on the principle of equivalent substitution, this paper realizes the exchange of additive points and branch points, which can not be directly exchanged between them, standardizes classical cybernetics and modern cybernetics into simple systems and complex system control theories, respectively, based on the characteristics of the times. The definitions of closed loop and open loop are clarified, the maximum overshoot and stability margin are normalized to maximum overshoot ratio and stable margin respectively according to the definition, and the arrangement order of Nyquist diagram and Bode diagram is analyzed, which can be understood according to two ideas. These innovations make the subject easier to learn and study.
