Modeling, simulation, and integrated guidance-control of a kinetic warhead utilizing moving-mass actuators are discussed. Moving masses can be used in any speed range both in the atmosphere as well as outside it, as long as there is a force, either aerodynamic or propulsive, acting on the vehicle. The moving-mass actuation technique offers significant advantages over conventional aerodynamic co...

This article presents modelling and control of a climatic chamber with on/off actuators. Controlled environmental variables in the chamber are temperature, relative humidity and illumination. The system is first decoupled by nonlinear transformation and a linear model is identified using subspace methods; further, a model predictive control strategy for processes with on/off actuators is presen...

It is well known that three momentum wheel actuators can be used to control the attitude of a rigid spacecraft and that arbitrary reorientation maneuvers of the spacecraft can be accomplished using smooth feedback. If failure of one of the momentum wheel actuators occurs, we demonstrate that two momentum wheel actuators can be used to control the attitude of a rigid spacecraft and that arbitrar...

Thrust vector control (TVC) is a prime example of an aerospace system in which electromechanical actuators (EMAs) can potentially be effective. Researchers at NASA’s Marshall Space Flight Center are currently developing EMAs to replace the hydraulic servo actuators for use on space vehicles with TVC. The current paper focuses on the control of EMAs in TVC applications and on the optimization of...

The intelligent control of autonomous vehicles is one of the most important challenges that intelligent transport systems face today. The application of artificial intelligence techniques to the automatic management of vehicle actuators enables the different Advanced Driver Assistance Systems (ADAS) or even autonomous driving systems, to perform a low level management in a very similar way to t...
