| Abstract: This paper describes an inertial stabilized rifle where a recurve actuator, constructed from piezoelectric material, is used to internially stabilize the barrel assembly of a tactical rifle to compensate for the small user-induced disturbances. This system is an active stabilization system designed to decouple the shooter’s interruption effects from the barrel movement based on control systems. Based on the feedback of the targeting error from the sensors, a control system will calculate the desired displacement and force needed to cancel out the human disturbances that are imparted to the rifle. The actuators are designed to cancel out jitter disturbances in a frequency range of 0Hz-5Hz It presents research to help protect and increase the defenses of soldiers on ground. While in battle these soldiers’ defenses and performance suffer due the intense stressors of combat. A different method for mitigating the depredating physiological effects of a soldier's marksmanship due to battle stressors can be achieved through the design and implementation of active stabilization system for small arms weapons. Combat stress may be defined as the perception of an imminent threat of serious personal injury or death, or the stress of being tasked with the responsibility to protect another party from imminent and serious injury or death, under conditions where response time is minimal. Physiological effects that result from combat include, but are not limited to, a dramatic increase in heart rate, heavy breathing, muscle tremors, and anxiety. The requirements of this system are discussed and the actuator controller are derived. This research uses pole-placement control techniques to develop control algorithms for simulation. The level of performance for the control algorithm is based on how well measure up to the criteria developed from the rifle. | ||
