Adaptive Stabilization of Discrete Linear Systems via a Multiestimation Scheme
نویسندگان
چکیده
A pole-placement based adaptive controller synthesized from a multiestimation scheme is designed for linear time-invariant plants. A higher level switching structure between the various estimation schemes is used to supervise the reparametrization of the adaptive controller in real time. The basic usefulness of the proposed scheme is to improve the transient behavior so that the closed loop stability is guaranteed. The scheme becomes specifically attractive when extended to linear plants whose parameters are piecewise constant while changing abruptly to new constant parametrizations or when they are time-varying. A complete description of the controller architecture with its associated multiestimation scheme is given. Also, the proofs of boundedness of all the relevant closed-loop signals are given so that the closed-loop system is stable.

Robustly Stable Multiestimation Scheme for Adaptive Control and Identification with Model Reduction Issues
A discrete pole-placement-based and multiestimation-based adaptive control scheme involving a relative adaptation dead zone is presented for a plant with known poles and unknown zeros. The basic usefulness of the proposed multiestimation scheme is related to the use of a set of models of reduced order associated with the multiestimation scheme instead of a high-order one. Depending on the frequ...
متن کاملA new switching strategy for exponential stabilization of uncertain discrete-time switched linear systems in guaranteed cost control problem
Uncertain switched linear systems are known as an important class of control systems. Performance of these systems is affected by uncertainties and its stabilization is a main concern of recent studies. Existing work on stabilization of these systems only provides asymptotical stabilization via designing switching strategy and state-feedback controller. In this paper, a new switching strate...
متن کاملAdaptive Stabilization for Non-controllable Time-varying Plants by Using Multiestimation
This paper presents an indirect adaptive control scheme for nominally stabilizable, but possible non-controllable, continuous and timevarying systems with unmodelled dynamics. The control objective is the adaptive stabilization of the system. The scheme includes several estimation algorithms and a supervisor which selects the appropriate estimator keeping it in operation during at least a minim...
متن کاملEigenvalue Assignment Of Discrete-Time Linear Systems With State And Input Time-Delays
Time-delays are important components of many dynamical systems that describe coupling or interconnection between dynamics, propagation or transport phenomena, and heredity and competition in population dynamics. The stabilization with time delay in observation or control represents difficult mathematical challenges in the control of distributed parameter systems. It is well-known that the stabi...
متن کاملRobust adaptive control of linear time-delay systems with point time-varying delays via multiestimation
This paper presents an adaptive pole-placement based controller for continuous-time linear systems with unknown and eventually time-varying point delays under uncertainties consisting of unmodeled dynamics and eventual bounded disturbances. A multiestimation scheme is designed for improving the identification error performance and then to deal with possibly errors between the true basic delay c...
