摘要：
A LQ-PID controller guarantees the stability and robustness. The plant and the controller of it seem stable but it is possible that they are unstable internally. Therefore, this study considered the possibility that a system can be internally unstable. This study evaluated a method to reinforce the stability by using an internal stability utilizing the small gain theorem in the H-infinity controller problem of design problem, which assures the robustness.
