The Takagi-Sugeno (T-S) fuzzy multiple-variable integral control system with fuzzy state observer is designed for the coordinated control of multi-input-multi-output (MIMO) nonlinear boilerturbine system whose operating points vary within a wide range. Linear models are first derived from the original nonlinear model on several operating points. Next the fuzzy multi-variable integral controller...

We consider a special class of port-Hamiltonian systems for which we propose a design methodology for constructing globally exponentially stable full-order observers using a passivity based approach. The essential idea is to make the augmented system consisting of the plant and the observer dynamics to become strictly passive with respect to an invariant manifold defined on the extended state-s...

This paper presents the LQ-Servo control with observer for TCP/AQM system. In order to estimate the state of TCP window packet size, the control structure is extended with observer based on Kalman filter.

The problem of the construction of a Logic Observer, which generates a sequence of propositions that correctly describe system state properties, is mainly intended to solve the state estimate of nite state machines. Of particular interest is the convergence of the logicbased dynamical system statements (in an appropriate sense) to true characterizations of the system state. This paper demonstra...

In the classical theory of finite-dimensional linear time-invariant systems in state space form the term deterministic separation principle refers to the observation that a stabilizing output feedback controller can be constructed by first constructing an asymptotic state observer that is then coupled to a stabilizing state feedback controller. In this paper we discuss the following converse pr...

We propose a simple abstract formalisation of the act of observation, in which the system and the observer are assumed to be in a pure state and their interaction deterministically changes the states such that the outcome can be read from the state of the observer after the interaction. If the observer consistently realizes the outcome which maximizes the likelihood ratio that the outcome perta...

Control and observation are in general not dual problems. While the pole placement parts of the classical static state feedback control problem on the one hand and the classical full state observer problem on the other hand are dual in the classical sense (in the context of linear time-invariant plants in input/state/output form), this is not true for the full state feedback control/state obser...
