The U.S. Army has built a test fixture called ATB1000 which emulates the types of nonlinearities and flexibilities found on most lightweight turreted weapon systems. In this study, the Trajectory Pattern Method is used to synthesize motion trajectories and generate inverse dynamics model based feedforward actuating signals for the test fixture. The main contribution of the present study is the derivation of the inverse dynamics model of the system in ...
In this paper, active control of flexible structures, e.g., weapon systems, using feedback and feedforward compensation is considered. Specifically, dynamic feedback design utilizing signals from the accelerometer mounted on the structure is discussed. Furthermore, utilization of adaptive input precompensators in conjunction with nonlinear controllers for flexible structures is proposed. The flexible pointing system considered here is the test-bed at the Army Research Development Engineering Center (ARDEC) at Picatinny Arsenal, which ...
