Abstract : The report studies the roll loop of an operational surface to air missile as an example of a typical self adaptive control system. The missile studied also exhibits a phenomenum called roll wander, a low frequency oscillation in missile roll orientation. Because of this, the report is developed in three major areas of study. First, is the study of the missile roll control loop. Second, is a study of the phenomenon of roll wander, with the production of this phenomenon in the computer simulation. Third and finally is the implementation, in the computer simulation, of a self adaptive notch filter to suppress the occurence of roll wander. (Author)
