Hybrid feedback stabilization of rotational–translational actuator (RTAC) system
(John Wiley & Sons, Ltd., 1998-04-15)
A hybrid feedback control law is proposed for the RTAC system. This hybrid feedback control law is expressed in terms of a continuous feedback part and a part that includes switched parameters determined according to a ...
H2-suboptimal stable stabilization,
(Elsevier, 1994-11)
In this paper we present two approaches for designing H2-suboptimal stable controllers. Both full-order and reduced-order controllers are considered.
Fast reference governors for systems with state and control constraints and disturbance inputs
(John Wiley & Sons, Ltd., 1999-12-30)
Reference governors are applied to closed-loop tracking systems that are linear and discrete time and have constraints on state and control variables. Earlier results are extended in significant ways. Disturbance inputs, ...
Guaranteed cost inequalities for robust stability and performance analysis
(John Wiley & Sons, Ltd., 2002-12-30)
In this paper, we formulate robust stability and performance bounds in terms of guaranteed cost inequalities. We derive new guaranteed cost bounds for plants with real structured uncertainty, and we reformulate them as ...
Feedback stabilization of control systems described by a class of nonlinear differential-algebraic equations
(Elsevier, 1990-07)
A theoretical framework for the stabilization of control systems defined by a class of nonlinear differential-algebraic equations is established. Assumptions are stated which guarantee that the nonlinear differential-algebaric ...
Lyapunov-stable discrete-time model reference adaptive control
(John Wiley & Sons, Ltd., 2005-12)
Discrete-time model reference adaptive control (MRAC) is considered with both least squares and projection algorithm parameter identification. For both cases complete Lyapunov proofs are given for stability and convergence. ...
Optimal hold functions for sampled data regulation
(Elsevier, 1991-01)
This paper investigates the use of Generalized Sampled Data Hold Function Control (GSHF) to optimize quadratic measures of performance in sampled data control loops. The idea of GSHF control is to use sampled data feedback, ...
Parameter-dependent Lyapunov functions and the discrete-time Popov criterion for robust analysis,
(Elsevier, 1994-06)
Parameter-dependent Lyapunov functions are developed for discrete-time systems with constant real parameter uncertainty. This construction of a family of Lyapunov functions is then used to analyze robust stability with H2 ...
A riccati equation approach to the singular LQG problem
(Elsevier, 1993-05)
The problem of optimal fixed-order dynamic compensation for the singular LQG problem is considered. Necessary conditions characterizing the optimal compensator for the case involving both singular measurement noise and ...
Vehicle cruise: Improved fuel economy by periodic control,
(Elsevier, 1976-03)
It is shown that time-dependent periodic control can improve the fuel economy of vehicles in cruise. The time-dependent controls considered are relaxed steady-state (RSS) control, quasi-steady-state (QSS) control and ...
