Background information on missile autopilots and bank-to-turn steering is given by covering the following topics: where the autopilots fits into the overall command guidance loop; performance requirements, objectives and design problems; the different types of autopilots and their basic design; and a comparison of bank-to-turn and skid-to-turn steering, outlining the advantages and disadvantages of each and looking at experimental evidence that demonstrates the superior aerodynamic properties of certain asymmetrical missiles over circular bodies. The aerodynamic transfer functions, including some of the cross coupling terms, are derived from first principles to allow a relatively 'simplified' (although still very complex) coupled bank-to-turn autopilot to be designed, modeled and analyzed on MATLAB (a computer software package designed for analysis of control systems in block diagram form) for a specific missile design and operating point. The responses of the missile to specific demands are then found and compared for the missile in a bank-to-turn and skid-to-turn configuration. This exercise demonstrates some of the problems involved in the design of a coupled bank-to-turn autopilot and the implementation of the design on conventional software programs.
