Control zeros and maximum-accuracy/maximum-speed control of LTI MIMO discrete-time systems
نویسنده
چکیده
Based on new definitions of “control zeros” and minimum phase property for possibly nonsquare LTI MIMO discretetime systems, generalizations of perfect regulation and perfect filtering are presented both for polynomial matrix and state space models. Consequently, general equivalence results are announced for multi-step and single-step optimal controls as well as for maximumaccuracy and maximum-speed controls for LTI MIMO discrete-time systems. The latter is made visible after the introduction of a new category of time-optimal control, namely infimum-time control. The equivalence conditions refer to the system’s right-invertibility and the (newly-defined) minimum phase behavior, which demonstrates the usefulness of the new approach to zeros of multivariable systems.

A Smith Factorization Approach to Robust Minimum Variance Control of Nonsquare LTI MIMO Systems
The minimum phase systems have ultimately been redefined for LTI discrete-time systems, at first SISO and later square MIMO ones, as those systems for which minimum variance control (MVC) is asymptotically stable, or in other words those systems who have ‘stable’ zeros, or at last as ‘stably invertible’ systems. The redefinition has soon been extended to nonsquare discrete-time LTI MIMO systems...
متن کاملZeros, Output-Nulling Subspaces and Zero Dynamics in MIMO LTI Systems
In standard MIMO LTI continuous-time systems S(A,B,C) the classical notion of the Smith zeros does not characterize fully the output-zeroing problem nor the zero dynamics. The question how this notion can be extended and related to the state-space methods is discussed. Nothing is assumed about the relationship of the number of inputs to the number of outputs nor about the normal rank of the und...
متن کاملRobust Model Predictive Control for a Class of Discrete Nonlinear systems
This paper presents a robust model predictive control scheme for a class of discrete-time nonlinear systems subject to state and input constraints. Each subsystem is composed of a nominal LTI part and an additive uncertain non-linear time-varying function which satisfies a quadratic constraint. Using the dual-mode MPC stability theory, a sufficient condition is constructed for synthesizing the ...
متن کاملOn the Pole Assignment for Linear Time Invariant (LTI), Discrete Time and Continuous Time Multiple Inputs Multiple Outputs (MIMO) Systems via Output Feedback Control
In this brief, the problem of the pole assignment of a linear time invariant (LTI), discrete/continuous multiple inputs/multiple outputs (MIMO) time system via output feedback is considered. The problem is reduced to the minimization of the distance of the desired characteristic polynomial from the characteristic polynomial of the under output feedback control law system at the unit circle. Num...
متن کاملAIOSC: Analytical Integer Word-length Optimization based on System Characteristics for Recursive Fixed-point LTI Systems
The integer word-length optimization known as range analysis (RA) of the fixed-point designs is a challenging problem in high level synthesis and optimization of linear-time-invariant (LTI) systems. The analysis has significant effects on the resource usage, accuracy and efficiency of the final implementation, as well as the optimization time. Conventional methods in recursive LTI systems suffe...
