Elevation axis model of a barrel stabilization system is constructed. The
nonlinearities which are considered in the model are orifice flow
characteristics, coulomb friction, hard-stop limits, kinematics of the system
and unbalance on the barrel. A Simulink® / model for the servo valve,
actuation system and barrel is constructed. Servo valve identification is
made via the actual test data. Compressibility of the hydraulic fluid is taken
into consideration while modeling the actuation system. Friction model is
simulated for different cases. Controller of the system is constructed by two
PIDs, one for each of the velocity and the position loops. Velocity feed
forward can reduce the time to make a quick move by the system. The
disturbance is evaluated from a given road profile and disturbance feed
forward is applied to the system.
