Modeling, simulation and control of armament systems

in The rotor Z/N per rev disturbance and the firing disturbance represent major periodic disturbances, whereas wind gusts represent major stochastic disturbances. Compensation for body motion and target motion are also considered as measured disturbances for pointing control. The particular tests reported here were conducted at the Ware Simulation Laboratory, Rock Island Arsenal. The single barrel weapon was mounted in a specially fabricated saddle and placed in the Universal Turret System (UTSI which was originally designed for a gatling gun. The UTS was mounted on the front-end of a helicopter. This frontend was mounted on a six-degree-of-freedom fixed simulator controlled by a hydraulic actuation system. The simulator was capable of creating body motion torques typical of various flight conditions. Objectives for the test were as follows: Demonstrate the lowest possible dispersion with Design and demonstrate linearizing controller, Establish guidelines for successful flight tests, and Evaluate requirements for adaptive control. multiple rounds,
