The robust control of missiles is a multidisciplinary challenge in dynamics, aerodynamics, propulsion, and controls. Figure 15.1 illustrates an artist’s conception of a high-performance agile missile. The understanding and modeling of these disciplines are critical in the development of a missile’s ight control system. The control software (guidance and ight control) that controls the weapon system during ight is the linkage that connects these disciplines and makes the system perform as required. This chapter will discuss these disciplines and practical considerations in the control of missiles and guided munitions from a control engineer’s perspective.
