利用计算机完成控制系统的根轨迹作图，了解控制系统根轨迹图的一般规律，利用根轨迹进行系统分析。 (Using computer control system for the completion of the root locus mapping to understand the control system of the root locus of the general laws, the use of a systematic analysis of the root locus.)

A programmable-logic controller (PLC) is a compact computer-based electronic system that uses digital or analog input/output modules to control machines, processes, and other control modules. A PLC is able to receive (input) and transmit (output) various types of electrical and electronic signals and use them to control and monitor practically any kind of mechanical and/or electrical system.
