Modelling and analysis of inertia self‐tuning phase control strategy for a floating multi‐body wave energy converter

IET Renewable Power Generation, 2021
Wave energy converters (WECs) exhibit higher energy capture capacity when the wave frequency is close to the nature frequency of the device. A possible way to enhance energy capture efficiency is to modify the nature frequency of a WEC to match the ...

Research on adaptive cruise control algorithm considering road conditions

IET Intelligent Transport Systems, 2021
As one of the most important ADAS systems, traditional adaptive cruise control is only suitable for relatively simple working conditions such as expressways, and it is difficult to deal with complex traffic environment and road working conditions.
