Attitude estimation is one of the key technologies for satellite navigation, and a traditional Kalman filter (KF) can spit out good results under normal conditions. However, uncertainties or measurement faults may occur affect accuracy, especially small with few sensors. In this article, robust-extended (REKF) developed attitude equipped only three-axis magnetometer. By adjusting gain via single scale factor (SSF), newly compensate faults. order to correct different state variables by...
A new power system distance relay is developed in this paper. The based on two operation criteria: a current criterion; and voltage criterion. Each uses the fault component as operating quantity, reacts only reactance of transmission line. So, it relay. During external faults, criteria are complementary to each other, i.e. at least one them will not be satisfied; so no maloperation occur. internal both satisfied even if resistance high.
In this paper, we investigate a planar parallel mechanism called five-bar which is used in wire bonders of semiconductor packaging system where the required accuracy about 2 (um), acceleration reaches 10–15 (g). However, conventional modeling and analyzing methods that treat all components manipulator as rigid ignore possible deformations, definitely are insufficient to satisfy those rigorous demands. Thus, dynamic model with consideration both motion flexible displacement developed for...
Transmission line fault location is one of the essential steps to ensure power supply reliability. Traditional model based methods and traveling wave have limitations such as requirements accurate parameters or high sampling rates. Existing data-driven usually require large number training data that are exactly consistent with practical system. However, in systems quite limited, there could be mismatch between system simulation system, limiting accuracy. To this end, paper proposes a...
