Guidance Algorithm for an Air-to-Air Boost Phase Interceptor

Current Ballistic Missile (BM) defence systems intercept an incoming threat in its terminal phase, and to some extend during its coast phase. During the boost phase of a BM, the initial velocity of the BM is low and the hot exhaust plume is easy to spot for infrared sensors, which provides a good opportunity for interception. To do so, the...

Distributed State Estimation for Medium-Fidelity Wind Farm Models in pursuit of Model-Based Closed-Loop Control

In research, the overall power production in a wind farm is typically increased by employing model-based wind farm control. A controller, in an open-loop setting, operates based on the velocity of the wind flow, predicted by a wind farm model. For a controller to achieve the desired level of power production, a wind farm model has to be accurate...

SPS-2: Attitude Control System Design for the Science Mode

Spacecraft attitude refers to the orientation of the spacecraft body axes with respect to the inertial reference frame. Attitude determination and control is the estimation of the current orientation of a satellite and controlling or changing it on demand to reach a desired orientation. The SPS-2 Attitude Control System consists of four modes:...

Deconvolution Filters for Dynamic Rocket Thrust Measurements

Every spacecraft carries small rocket engines called thrusters for the purpose of orbit and position corrections in space. A precise operation of the thrusters saves fuel and a lower fuel consumption can extend the service life of the spacecraft. Precise thrust levels can be better obtained by pulsed firing than by continuous firing of the...
