Some recent results from research conducted in the EMC group at Okayama Universiry are reviewed A scheme for power-bus modeling with an analytical method is introduced. A linear macro-model for ICdLSIs. called the LECCS model, has been developed for EM and EMS simulation. This model has a very simple structure and is suficiently accurate. Combining the(More)
According to the active power balance principle, the paper analyzed the approximate mathematical model of APF. In order to optimize the control effect of dc bus voltage in APF, PID control method based on improved BP neural network is adopted to do closed-loop control to the system. The two strategies, adding momentum method and adaptive learning rate(More)
YOELECTRIC (EMG) and nerve action potential (NAP) recordings are often used to diagnose patients with neuromuscular diseases and disorders. The study of peripheral neuropathy, motoneuron disease, and muscular dystrophy can be improved through the use of animal models that present similar phenotypic signs such as gradual denervation of muscle and axonal(More)
In this paper, it is discussed from the aspects of the operation requirements in Microgrid and the control methods in power system, focusing on the idea of how to make the inverter imitate the output characteristics of the synchronous generator. The fundamental difference between Microgrid and the power grid lies in the hardware interface, one is the(More)
Grid fault is a challenge for electrical equipments in operating and control stably. In order to enhance the reliable operation of network equipments, grid frequency, phase angle and amplitude tracking must be fast dynamic respond performance and high detection accuracy under various grid faults. So that the appropriate control measures can be taken timely.(More)
