Weight Selection in H-/spl infin/ Loop Shaping Using Lead/Lag Compensators

In this paper a systematic approach for weight selection has been applied. A classical phase lead compensator is used as weight (precompensator) in Hinfin loop shaping for design of pitch controller for air vehicle. Analysis has been confined only to bode plots. The analysis and results achieved indicate that Hinfin loop shaping control theory is a viable tool for design and synthesis of attitude control of air vehicle
