摘要：
This paper presents a practical methodology to analyze the stability of a control loop consisting of a continuous time plant and a discrete PID controller connected as a NCS. With this methodology, it is possible to extend useful modern techniques like lifting systems developed for memory-less controllers to cover practical control loops. The methodology is demonstrated with a real-time simulation of a representative system, using a NCS test bench. (C) 2015 Elsevier Ltd. All rights reserved.
