Automatic Gain Control for Unity Feedback Control Systems

“…It becomes an AGC loop with i V and c V . Note that the system described by Fig.1a without K(s) is equivalent to the conventional Automatic Gain Control (AGC) loop for processing radio or video signal [1][2][3][4][5][6][7][8][9]. i V is the receiving signal for processing.…”

“…The fast loop is used for command tracking. The overall system is equivalent to a conventional Automatic Gain Control (AGC) loop [1][2][3][4][5][6][7][8][9] with command tracking error input. Therefore, it will give good command tracking behavior while keeping robust characteristic of the original AGC loop, especially for the system with fast large parameter variations.…”

“…Analyzing techniques and stability of the AGC loop are well developed for variations of receiving radio and video signals [1][2][3][4][5][6][7][8][9]. In this paper, the stability of the controlled system with the proposed control will be verified by linearized systems.…”

Analysis and Design of Feedback Control Systems With Tracking Errors Square

“…4 and 5 show variations of V c that are much slower than those of V i s'. This is a basic property of the AGC loop [1][2][3][4][5][6][7][8][9][10][11][12][13][14] and adaptive control schemes [17]. Now, consider an electro-hydraulic velocity servo system [18,19] shown in Fig.…”

“…AGC loops are used in virtually all modern communication/video/image systems. The analyzing techniques and stability are well developed and discussed [1][2][3][4][5][6][7][8][9][10][11][12][13][14] for variations of receiving audio/video signals. In this study, stability of the proposed control system will be verified by linearized systems that are perturbed derived from equilibrium conditions (or steady-state conditions).…”
