Design and Analysis of Discrete Lateral Autopilots for Coordinated Bank- to-Turn Missiles

Abstract

This thesis addresses the design and analysis of discrete lateral autopilots for application to BTT missiles. The first part reviews the classical design and analysis of the continuous uncoupled yaw and roll channels. Then, applying analog-to-digital conversion, the corresponding discrete autopilots were designed and analyzed in terms of their transient responses. The second part uses modern control design techniques for the single-input discrete lateral autopilots. At first, assuming availability of all states for feedback purposes, a discrete state-feedback autopilot is obtained. Next, since the state vector is not always available to direct measurement, an estimator is introduced to implement control. The state-feedback and estimator designs are analyzed for both lateral channels and found to have satisfactory time responses. Finally, coupling the discrete pitch and roll channel autopilots, a state-feedback and estimator are designed and found to be robust. Keywords: Bank to turn; Autopilot; Yaw; Roll; Pitch motions; Estimator robustness. (Theses)
