This paper comparatively analyzes the performance of X-MAC and PW-MAC as asynchronous sensor MACs with tree-topology using virtual simulation. PW-MAC has better performance in comparison to X-MAC, but it is receiver-initiated and shows collision when data is sent to common receiver. Therefore, this study evaluates whether PW-MAC maintains better performance(More)
This paper proposes the vehicle longitudinal controller for the Anti-lock Braking System(ABS) and Traction Control System(TCS). The sliding mode control scheme without a sign function is used to design a controller. Instead of a sign function, the adaptation mechanism is used to reduce the actuator chattering as a problem of the sliding mode control. The(More)
— Gearshift control is one of the main functions of automotive transmissions. The proposed control utilizes the functionality of Dual Clutch Transmissions (DCTs) that two control inputs are available incorporating each other. During gearshift operation, each clutch is controlled uni-directionally to prevent undesirable effects such as dead zone(More)
—This paper presents a novel disturbance compensation scheme to attenuate periodic disturbances on repetitive motion using permanent magnet linear synchronous motors (PMLSMs), and this scheme is called the periodical adaptive disturbance observer. The scheme is based on assumptions that all measured states and disturbances are periodic and repetitive when(More)
— The airbag system has been a standard safety equipment for vehicles and it is efficient for enhancing the safety of a driver and passengers from crash. However, inadvertent injuries have been caused by airbag deployment in a rough and uncertain temporal interval. In this paper, a pre-crash discrimination system is proposed to prevent airbag deployment(More)
—This paper proposes a periodic adaptive disturbance observer (PADOB) for a precision position control of a PMLSM (Permanent Magnet Linear Synchronous Motor), which is based on a periodic adaptive learning control(PALC). It updates the output of a classical linear DOB to compensate modeling errors between a nominal plant and actual plant and external(More)
—Airbag systems have become an essential safety device for guaranteeing the physical well-being of drivers and their passengers. Unlike other safety devices, airbags are used as the last resort in a collision, and because they are directly linked to the life of the driver and passengers, the proper functioning of the system is an issue of paramount(More)
— This paper proposes a periodic adaptive disturbance observer (PADOB) to control a PMLSM (Permanent Magnet Linear Synchronous Motor). The PADOB consists of a classical linear DOB and an adaptive mechanism which has been known as the periodic adaptive learning control (PALC). The key idea is to compensate parametric errors between the actual plant and the(More)
Milk-related traits (milk yield, fat and protein) have been crucial to selection of Holstein. It is essential to find the current selection trends of Holstein. Despite this, uncovering the current trends of selection have been ignored in previous studies. We suggest a new formula to detect the current selection trends based on single nucleotide(More)
