Optimal 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...
متن کاملA Robust Control Design Technique for Discrete-Time Systems
A robust state feedback design subject to placement of the closed loop eigenvalues in a prescribed region of unit circle is presented. Quantitative measures of robustness and disturbance rejection are investigated. A stochastic optimization algorithm is used to effect trade-off between the free design parameters and to accomplish all the design criteria. A numerical example is given to illustra...
متن کاملOn the Design of Nonlinear Discrete-Time Adaptive Controller for damaged Airplane
airplane in presence of asymmetric left-wing damaged. Variations of the aerodynamic parameters, mass and moments of inertia, and the center of gravity due to damage are all considered in the nonlinear mathematical modeling. The proposed discrete-time nonlinear MRAC algorithm applies the recursive least square (RLS) algorithm as a parameter estimator as well as the error between the real ...
متن کاملParameter Estimation for Discrete-Time Nonlinear Systems Using EM
In this paper we consider parameter estimation of general stochastic nonlinear statespace models using the Maximum Likelihood method. This is accomplished via the employment of an Expectation Maximisation algorithm, where the essential components involve a particle smoother for the expectation step, and a gradient-based search for the maximisation step. The utility of this method is illustrated...
متن کاملAdaptive Algorithms for Paso Systems Adaptive Algorithms for Paso Systems
We describe a fault-tolerant distributed storage system for local area networks. Our system implements Persistent, Associative, Shared Object (PASO) memory. A PASO memory stores a set of data objects that can be accessed by associative search queries from all nodes in an ensemble of machines. This approach to distributed memory has been used in a number of systems, and provides a convenient and...
