Paper Abstract

Mobile platforms with heavy, high powered payloads, such as long range laser designators and directed energy weapons, require precision control of pointing in the presence of base motion disturbances. Wideband motion stabilization and target traking control systems with high dynamic gain are required. Cascading multiple integrators in the forward loop, for example, is a direct, commonly used technique for obtaining the loop gain required to achieve stabilization accuracy. This often leads, however, to stability problems and constraints on system bandwidth. The motion stabilized EO tracking and pointing control system design described in this paper uses a unique, supervisory control approach to achieve wideband pointing accuracy. The control system described is an extension of previously developed and fielded weapon pointing control systems.

The model based tracking and feed forward methods, used to achieve high dynamic pointing and tracking accuracy without the destabilizing effect of excessive gain, are presented. The basic system configuration and the concept of a central electro—optical Stable Sensor System controller are described and demonstrated with a simple tracking scenario.
