Autonomous Navigation for Binary Asteroid Landing: A vision-based and altimeter-aided navigation filter for small spacecraft

This paper investigates the performance of an autonomous navigation system to navigate a spacecraft in the proximity of a binary asteroid system using optical and laser ranging measurements. The knowledge about the binary asteroid is limited to its orbital parameters and ellipsoid shape models. The accelerometer bias random walk is included in...

PMU-based state estimation for real-time monitoring of active distribution systems

State estimation (SE) is a crucial tool for power system state monitoring since the control center requires a process to deal with a large number of imprecise measurements. Several SE methods have been applied and developed for the electric power system in the transmission level in the past several decades. Meanwhile, SE for the distribution...

Attitude Estimation of a Quadcopter with one fully damaged rotor using on-board MARG Sensors

Quadcopters are becoming increasingly popular across diverse sectors such as mapping, photography, or surveillance. Since rotor damages occur frequently, it is essential to improve the attitude estimation and thus ultimately the ability to control a damaged quadcopter. The Control and Simulation group of TU Delft developed a quadcopter...

Measurement strategy for state estimation of medium voltage grids with distributed generation

The world is going through an energy transition towards decentralized electricity generation like photovoltaic systems and new loads like electric vehicles, which contribute to the variability of the operation state of distribution systems. To ensure future operation under safe and efficient conditions, it becomes increasingly important to have...

Observer-Based State of Balance Estimation of the Walking Human with Upper Body Inertial Measurement Unit Data

Knowledge of the state of balance of the moving human is essential for the design of fall detection algorithms and wearable robotic controllers for balance assistance. Still, there is no known general method to make an online estimation of the state of balance of the walking human, with the limited and local sensor measurements that are usually...
