A Steer-By-Wire (SBW) control scheme is proposed for enhancing the lateral stability and handling capability of a super lightweight vehicle by using the energy optimal control method. Tire dissipation power and virtual power, which is the product of yaw moment and the deviation of actual yaw rate from the target yaw rate, were selected as performance(More)
The purposes of this study are a) to determine whether homehelpers attend to drug-related service of elder care-recipients at home and b) to determine what cooperating human resources were utilized. A structured questionnaire survey was conducted in 1997 with 403 homehelpers who provided in home care to dependent elderly person. Of the total, 19% subjects(More)
This paper introduces the application of a newly developed optimal control method for an autonomous underwater vehicle (AUV) and actuator failure performance in case of the failure of either rudder or stern fin. The six degree-of-freedom (DOF) nonlinear equations of motion were used in the control. For failure and no-failure cases, two control system models(More)
