Delay-Adaptive Predictor with Estimation of Actuator State

Abstract

In Chapter 7 we solved the problem of adaptive stabilization in the presence of a long and unknown actuator delay, under the assumption that the actuator delay state is available for measurement. In this chapter we dispose of this assumption. The result that we obtain in this chapter is not global, as the problem where the actuator state is not measurable and the delay value is unknown at the same time is not solvable globally, since the problem is not linearly parametrized.
