A new robust adaptive control scheme for linear time varying plants
(2002)In a recent work, a new linear adaptive controller based on certainty-equivalence and backstepping design, which promises a level of transient and asymptotic performance comparable to that of the tuning functions adaptive ...

Non-identifier based adaptive control scheme with guaranteed stability
(2006)In this paper, we investigate a non-identifier based adaptive control scheme for single-input single-output (SISO) plants. The overall adaptive control system can be viewed as a feedback interconnection of a SISO plant, a ...

Nonconcurrent error correction in the presence of roundoff noise
(2006)This paper analyzes the effects of roundoff noise on our ability to nonconcurrently detect and identify transient faults that corrupt state variables during the operation of a fault-tolerant discrete-time (DT) linear ...

Nonconcurrent Error Detection and Correction in Fault-Tolerant Linear Finite-State Machines
(2003)In this paper, we construct fault-tolerant linear finite-state machines (LFSMs) in which error detection and correction can be performed nonconcurrently (e.g., periodically). More specifically, by jointly choosing the state ...

Nonlinear control design for linear time varying systems
(1996)A new class of linear controllers for linear time varying systems are proposed. These controllers are based on nonlinear tools such as integrator backstepping and nonlinear damping, and on a new filter structure that ...

On delayed observers for linear systems with unknown inputs
(2005)We present a method for constructing reduced-order state observers for linear systems with unknown inputs. Our design provides a characterization of observers with delay, which eases the established necessary conditions ...

On multiobjective H2/H∞ optimal control
(2001)In this paper the solutions to the optimal multiobjective H2/H∞ problem are characterized using Banach space duality theory, and shown to satisfy a flatness or allpass condition. Dual and predual spaces are identified, and ...

Robust adaptive attenuation of unknown periodic disturbances in uncertain multi-input multi-output systems
(2016)In high-performance high-accuracy systems, the attenuation of vibrational disturbances is essential. In this paper, we design and analyze a robust output-feedback adaptive control scheme to attenuate noise-corrupted ...

Robust adaptive sliding control of linearizable systems
(2001)A switching adaptive control algorithm based on a sliding mode method is proposed for a class of single-input, single-output nonlinear systems with unknown dynamics. The plant is assumed to be linear-in-the-control input ...

Robustness of the adaptive backstepping controllers for linear systems
(IEEE, 1997)In this paper, we present a unified procedure for designing and analyzing robust adaptive backstepping controllers for linear systems. Both the modular design and tuning functions design are considered. These controllers ...
