Adaptive control of unmanned aerial vehicles in atmospheric flight with reduced models
(2007)We propose an approximate implementation scheme for an adaptive linear quadratic control structure by employing a balanced truncation procedure in the loop prior to solving the associated Algebraic Riccati Equation (ARE). ...

Delayed observers for linear systems with unknown inputs
(2007)We present a method for constructing reduced-order state observers for linear systems with unknown inputs. Our approach provides a characterization of observers with delay, which eases the established necessary conditions ...

Encoded dynamics for fault tolerance linear finite-state machines
(2002)This note discusses fault tolerance in linear finite-state machines (LFSMs). By replacing a given LFSM with a larger, redundant LFSM that preserves the state of the original one in some linearly encoded form, various ...

Examples of optimal control for nonlinear stochastic control problems with partial information
(IEEE, 1995)Partially observable stochastic optimal control problems are considered. It is shown, via an information state approach and dynamic programming, that several classes of nonlinear systems with non-linearities in the dynamics ...

Finite-time disturbance attenuation control problem for singularly perturbed discrete-time systems
(1998)In this paper we consider the problem of finite-time H∞-optimal control of linear, singularly perturbed, discrete-time systems. The problem is addressed from the game theoretic approach. This leads to a singularly perturbed, ...

A new linear adaptive controller: Design, analysis and performance
(2000)The certainty equivalence and polynomial approach, widely used for designing adaptive controllers, leads to "simple" adaptive control designs that guarantee stability, asymptotic error convergence, and robustness, but not ...
