This study is concerned with the active control of a flexible arm using Q parameterization which is as one of form convex optimization. The nominal controller is the observer based controlier. It is designed based on an LQ servo strategy. Q parameterization can satisfy some constraints, for example, control input, overshoot, and settling time. However, Q parameterization becomes a higher-order compensator. It becomes from the 5th to the 40th-order in this study. The Q parameterization controller is also very robust.
