摘要

In this paper, a control system for the roll motion of an axisymmetric fin stabilized guidedammunition is presented. A gain scheduling will be defined in order to obtain the requiredperformance and robustness over a large envelope of flight conditions.A double proportional control loop was selected; in order to meet the specifications, thesizing of the parameters was performed using classical and modern robust theory techniques(LQR).To compare the two techniques, the control loops were reduced to equivalent SISO systemsthat ensure that the controller parameters have congruent physical meanings.LQR provided better results in terms of performances and robustness through the wholeflight envelope; moreover and since the results can be expressed analytically, itsimplementation will be straightforward.
