Eigenvalue 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 کاملDisturbance decoupling of multi-input multi-output discrete-time nonlinear systems by static measurement feedback
This paper addresses the disturbance decoupling problem (DDP) for nonlinear systems, extending the results for continuous-time systems into the discrete-time case. Sufficient conditions are given for the solvability of the problem. The notion of the rank of a one-form is used to find the static measurement feedback that solves the DDP whenever possible. Moreover, necessary and sufficient condit...
متن کاملInput-output decoupling of discrete-time nonlinear systems by measurement feedback
This paper addresses the input-output decoupling problem for discrete-time nonlinear systems by measurement feedback. Necessary and sufficient conditions are given to solve the problem by static or dynamic measurement feedback, respectively. Since the dynamic measurement solution presented here depends on the solution of the input-output linearization problem, a sufficient condition for lineari...
متن کاملRobust Input-Output Decoupling via Static Measurement Output Feedback
In this paper the problem of robust input-output decoupling for linear systems with nonlinear uncertain structure (NLUS), via an independent from the uncertainties static measurement output feedback law, is studied. The necessary and sufficient conditions for the problem to have a solution, are established. The general analytical expressions of the feedback matrices and the decoupled closed loo...
متن کاملDesign and Implementation of Discrete Time Observer Based Backstepping Controller for a 2DOF Servomechanism
The two degrees of freedom servomechanism has many applications, including in gimbaled seekers. These mechanisms require closed-loop control to perform properly. In this paper, an observer-based multi-input-multi-output hybrid controller is designed for a two-degree-of-freedom servomechanism. Since in the model presented in this paper, disturbances on the mechanism are considered, so an extende...
