Abstract :
This paper investigates the stability of multiloop LQ regulators when various combinations of actuator failures occur. It is proved that the closed-loop stability can be maintained under certain conditions by inserting appropriate constant gains in the control loops. The results are also applicable (via duality) to the design of state estimators which maintain stability in face of sensor failures.
