The study of flapped fin service system of main/flapped fin stabilizer

The paper studies the control law of flapped fin service system in the joint control system of main/flapped fin stabilizer. LQ inverse design based on pole placement method is used by means of state feedback inverse design. /spl Hscr//sup /spl infin// control theory is also adopted to design flapped fin service system. Both the simulation results are given and contrasted with result designed by classical control theory. So the two modern control theory advantages are concluded.
