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 کاملRobust stabilization of discrete-time periodic linear systems for tracking and disturbance rejection
In analogy to the Kučera-Youla parametrization we construct and parametrize all stabilizing controllers of a stabilizable linear periodic discrete-time input/output system, the plant. We establish a necessary and sufficient algebraic condition for the existence of controllers among these for which the output of the plant tracks a given reference signal in spite of disturbance signals on the inp...
متن کاملAdaptive Narrow Band Disturbance Rejection in Active Vibration Control
This paper presents a methodology for feedback adaptive control of active vibration attenuation systems in the presence of unknown narrow band disturbances. The proposed methodology consists in two algorithms based on the Internal Model Principle. The first one deals with an indirect adaptive control, the second one with a direct adaptive control. The feasibility of the two algorithms is illust...
متن کاملDISTURBANCE REJECTION IN NONLINEAR SYSTEMS USING NEURO-FUZZY MODEL
The problem of disturbance rejection in the control of nonlinear systems with additive disturbance generated by some unforced nonlinear systems, was formulated and solved by {itshape Mukhopadhyay} and {itshape Narendra}, they applied the idea of increasing the order of the system, using neural networks the model of multilayer perceptron on several systems of varying complexity, so the objective...
متن کاملReduced 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 ...
