Khalid A. Al Dakkan, Auteur ; Barth, Eric J., Auteur ; Michael Goldfarb |This paper proposes a control approach that can provide significant energy savings for the control of pneumatic servo systems. The control methodology is formulated by decoupling the standard four-way spool valve used for pneumatic servo control[...]![]()

Mark Adams, Auteur ; Barth, Eric J., Auteur |This paper presents a dynamic model of the interior ballistics of an experimental liquid propellant powered rifle. The liquid propellant powered rifle described utilizes a mixture of hydroxyl ammonium nitrate and hydrocarbon fuel to replace gunp[...]![]()

Xiangrong, Shen, Auteur ; Zhang, Jianlong, Auteur ; Barth, Eric J. ; Michael Goldfarb |This paper presents a control methodology that enables nonlinear model-based control of pulse width modulated (PWM) pneumatic servo actuators. An averaging approach is developed to describe the equivalent continuous-time dynamics of a PWM contro[...]![]()

Shields, Bobby L., Auteur ; Barth, Eric J., Auteur ; Michael Goldfarb |A methodology is proposed for the control of switching systems characterized by linear system dynamics with a time delay in the input channel. The method incorporates a state predictor that at each switching period determines the effect that the[...]![]()

Fite, Kevin B., Auteur ; Mitchell, Jason J., Auteur ; Barth, Eric J. ; Michael Goldfarb |This paper describes the modeling and control of a proportional-injector direct-injection monopropellant-powered actuator for use in power-autonomous human-scale mobile robots. The development and use of proportional (as opposed to solenoid) inj[...]
