Stability Analysis of Amplidyne Electrical Systems With Time-Varying Delay via a Matrix-Injection Method

This brief is concerned with the stability analysis of amplidyne electrcal systems (AESs) equipped with a delayed PI controller. Firstly, the model of AESs with time-varying delays and a PI controller is established. Secondly, a less conservative stability criterion of AESs related time delay is obt...

Summary:This brief is concerned with the stability analysis of amplidyne electrcal systems (AESs) equipped with a delayed PI controller. Firstly, the model of AESs with time-varying delays and a PI controller is established. Secondly, a less conservative stability criterion of AESs related time delay is obtained by utilizing an advanced matrix-injection method. Finally, the effectiveness of the proposed criterion is verified by a case study.
