Reduced order disturbance observer for discrete-time linear systems
In the paper, an output-based disturbance observer of reduced order is presented for a class of discretetime linear systems. First, a general form of a disturbance observer is proposed when full states are available. Then, by combining a state function estimator of minimal order, an output-based disturbance observer is derived. The existence condition will be formulated in the form of a static ...
متن کاملReduced-order disturbance observer design for discrete-time linear stochastic systems
The conventional disturbance observers for discrete-time linear stochastic systems assume that the system states are fully estimable and the disturbance estimate is dependent on the estimated system states, hereafter termed Full-Order Disturbance Observers (FODOs). This paper investigates the design of Reduced-Order Disturbance Observers (RODOs) when the system state variables are not fully est...
متن کاملState Estimation by Discrete Reduced Order UI Observer and Discrete Kalman Filter for Linear Systems
In this paper unknown input observer using projection operator method is used to estimate five states of the fifth order lateral axis model of L-1011 system in discrete domain. Discrete reduced order UI observer is used to estimate the states of the system in noiseless and noisy environment. Kalman filter has been designed to estimate the state of L-1011 system when noise is considered. Finally...
متن کاملFurther Results on Periodically Time-Varying Dynamical State-Feedback Controller Synthesis for Discrete-Time Linear Systems
In this paper, we enhance the quality of our preceding results on periodically time-varying dynamical state-feedback controller (PTVDSFC) synthesis for discrete-time linear periodic/time-invariant systems. We firstly revisit PTVDSFC synthesis for uncertainty-free systems and derive necessary and sufficient LMI conditions for the existence of the desired PTVDSFCs. Based on these LMIs, we next co...
متن کاملOptimal Finite-time Control of Positive Linear Discrete-time Systems
This paper considers solving optimization problem for linear discrete time systems such that closed-loop discrete-time system is positive (i.e., all of its state variables have non-negative values) and also finite-time stable. For this purpose, by considering a quadratic cost function, an optimal controller is designed such that in addition to minimizing the cost function, the positivity proper...
