This paper proposes a novel modulation technique that reduces both motor acoustic noise and switching loss. The conventional discontinuous PWM method can reduce the switching loss to a greater extent compared to the conventional three‐phase modulation method; however, the acoustic noise of the motor increases. The proposed technique adjusts the zero‐sequence voltage given to the voltage references...
Silver nanoink sinterable at low temperature, as low as 120degC, was developed from silver nanoparticle synthesized by thermal decomposition of silver complex. This ink has features of both low sintering temperature and excellent solution stability. Printed samples and some applications are described.
Traffic information feedback strategies have the potential to improve the efficiency of traffic flow. There is a processing delay in providing the information, and the delay sometimes makes the traffic flow unstable. In this study, a relationship between the stability of traffic flow of the Symmetrical Two-Route with providing traffic information and the information delay is analyzed. The type of...
This paper describes the rising up motion control for Denguribot. Denguribot is the Acrobot composed of 2 rounded links. The purpose of the rising up motion is to move Denguribot from a low energy state such as “sitting” to a high energy state such as “standing”. The control strategy is pumping up the system energy by swinging links. To swing links, the relative angle between 2 links is tracked to...
