Computer Simulation of a Cruise Missile Using Brushless DC Motor Fin Control.

This thesis describes a computer simulation developed in order to provide a method of establishing the potential of brushless DC motors for applications to tactical cruise missile control surface positioning. In particular an altitude hold controller has been developed that provides an operational load test condition for the evaluation of the electromechanical actuator. A proportional integral control scheme in conjunction with tachometer feedback provides the position control for the missile tailfin surfaces. The fin control system is further imbedded in a cruise missile model to allow altitude control of the missile. The load on the fin is developed from the dynamic fluid environment that the missile will be operating in and is proportional to such factors as fin size and air density. The program written in CSMP language is suitable for parametric studies including motor and torque load characteristics, and missile and control system parameters.
