Multivariable adaptive output-feedback control
Proceedings of the 2002 American Control Conference (IEEE Cat. No.CH37301), 2002In this paper, a new model reference adaptive output feedback controller is proposed for general multi-input multi-output (MIMO) systems with unknown parameters such that the tracking errors as well as the control gains remain uniformly bounded. First an adaptive observer is designed to estimate the state variables and system parameters from input ...

Modal control by output feedback
International Journal of Control, 1976A method is given for determining a general family of output feedback modal-control matrices of controllable and observable linear time-invariant systems. In addition, necessary conditions are established for stabilizing and arbitrarily assigning all eigenvalues by output feedback.

Nonlinear output feedback control
2005It is shown that the performance of a globally bounded (possibly dynamic) partial state feedback control of an input-output linearizable system can be recovered by a sufficiently fast high-gain observer. The performance recovery includes recovery of boundedness of trajectories, recovery of the property that the trajectories reach a certain set in ...

Static output feedback controllers: stability and convexity
IEEE Transactions on Automatic Control, 1998Summary: The main objective of this paper is to solve the following stabilizing output feedback control problem: Given matrices \((A,B_2,C_2)\) with appropriate dimensions, find (if one exists) a static output feedback gain \(L\) such that the closed-loop matrix \(A-B_2LC_2\) is asymptotically stable.

Sliding control using output feedback
Journal of Guidance, Control, and Dynamics, 1996We proposed a new sliding control method using output feedback that can guarantee global stability. The current scheme is very simple in structure because no observer is needed. The computational requirement is also very small. It is robust to all initial conditions, mismatched disturbance and parametric uncertainties.

Uncertain Systems: Output Feedback Control
2014This chapter finalizes some results of earlier chapters for systems that operate under set-membership uncertainty. Its aim is to emphasize a successful application of previously described techniques to such systems. The chapter thus gives a concise presentation of solution techniques for the problem of output feedback control based on available ...

UNIVERSAL OUTPUT-FEEDBACK SISO CONTROLLER
IFAC Proceedings Volumes, 2002Abstract A universal single-input-single-output (SISO) controller is proposed which is based on higher-order sliding modes and requires output measurements only. The uncertain SISO dynamic system to be controlled is required to have a permanent known-in-advance relative degree. Its exact mathematical model is not needed.

UNIVERSAL OUTPUT‐FEEDBACK SISO CONTROLLERS
Asian Journal of Control, 2003ABSTRACTIt is proved in the paper that practically all known higher‐order sliding controllers can be combined with recently developed 2‐sliding‐mode‐based differentiators yielding universal output‐feedback Single‐Input‐Single‐Output (SISO) controllers. These controllers can be applied at least locally, whenever the system relative degree is known.

2004
In previous chapters and [10, 11, 13, 14, 15], an inverse optimal PID controller was derived as a form of full state feedback one from the extended disturbance input-to-state stability and Open image in new window performance index. From now on, we are to make the PID state observer for an inverse optimal PID controller.

On linear output feedback control
IEEE Transactions on Circuits and Systems, 1986The paper presents an algorithm to determine linear output feedback gains to stabilize and/or arbitrarily assign the poles of a linear time-invariant system. Conditions for the feasibility of linear output feedback control are derived. The feasibility analysis and the control design procedure are based on the dynamics of the eigenvalues of the closed ...
