Automatic Control Of Aircraft & Missile ( Blakelock)

In this second edition all the material from the first edition has been retained and the errors found in the first edition have been corrected. Considerable new material has been added, as discussed in the following paragraph.

Chapter 7 has been expanded to cover the root locus analysis of a generic acceleration autopilot used in many air-to-air and surface-to-air guided missiles. The use of hinge moment commands to the canards for the control of missiles such as the AIM-9L Sidewinder is also covered. The guidance systems for these types of missiles as well as bank-to-turn missiles are covered in a new Chapter 8. The types of guidance include proportional navigation and line-of-sight and lead-angle command guidance. The discussion covers the complete root locus analysis of these guidance systems, and shows graphically why proportional navigation guidance is unstable for a . navigation constant less than one, where a value of one yields pure pursuit. The coupling of the output of a director fire control system in.to the autopilot is
