Any technical system is liable to the occurrence of faults. A major fault in the plant like the complete loss of an actuator or sensor breaks the control loop and renders the system in-operational, unless the control ...

A severe fault renders a system inoperable by breaking the control loops. The task of control reconfiguration is to change the control structure in order to bring the control back into operation. This paper introduces the concept of a "virtual actuator" that replaces the effect of broken actuators by using alternative control inputs. The stability of the reconfigured control loop is guaranteed if the faulty process is controllable.
This paper is concerned with the use of active brake systems in order to decrease the rollover risk of heavy vehicles. Since the forward velocity of the vehicle changes in time, the combined yaw-roll dynamic model has...

Any technical system is liable to the occurrence of faults. A major fault in the plant like the complete loss of an actuator or sensor breaks the control loop and renders the system in-operational, unless the control structure is changed in response to the fault. This paper shows how the LQG (linear quadratic Gaussian) optimal control problem can be posed and solved automatically for the faulty plant, resulting in a new controller that allows to stabilise the plant despite of an actuator fault. The same approach can be used to design a bank of observers (one per fault case) that can be used for sensor fault diagnosis and reconfiguration at the same time. The approach is experimentally verified at a two-degrees-of-freedom helicopter model.
In this paper a combined control structure with an active antiroll bar control and an active braking control is developed to decrease the rollover risk of heavy vehicles. This control structure also results in a fault...
