根据被控对象的要求和现实技术条件,总可以为一个自动调节系 统选择好执行元件、控制元件和敏感元件等。这样构成的系统可以称做原始系统,或未进行校正的系统。这样的系统一般是不能满足要求的。为了设计出满足静态和动态要求的系统,一般要用一些判据作基础,利用根轨迹法或频率法进行综合。 According to the requirements of the controlled object and the actual technical conditions, it is always possible to select an actuator, a control element and a sensitive element for an automatic adjustment system. The system thus constructed can be called an original system or a system without correction. Such systems are generally unable to meet the requirements. In order to design a system that satisfies the static and dynamic requirements, some criteria are generally used as a basis for synthesis using the root locus method or the frequency method.
