The present paper is concerned with an improvement of the so-called plant-input-mapping (PIM) discretization as applied to an analog controller that is used in a high-performance commercial driver for stepping motors. The controller employs a linearizing compensator to cancel out the effect of dead-zone nonlinearity that exists in a pulse-width-modulation circuit of the driver, which has been one...
PEOPLER-II is a hybrid robot with 8-leg ends and 4-wheels attached to a knee joint rim rotating around a hip joint. It has been developed to assist people who needs enhancement for their capability of locomotion. In order to cope with different environments, investigation of the robot trajectory is of significant importance while a frictional condition of the surface influences the form of trajectory...
The purpose of this paper is to study the stopping power of a plasma for a relativistic electron beam (REB) by taking into consideration the induction of an electromagnetic instability. Analyzing the electromagnetic instability in REB-plasma system, we consider a homogeneous, spacially infinite collisionless plasma. Ion motions are neglected throughout this paper. The dynamics of the system under...
