Tuning regulators for tracking MIMO positive LTI systems

چکیده
In this paper we consider the study of the servomechanism problem for multi-input multi-output (MIMO) linear time-invariant (LTI) positive systems. In particular, we present results on the tracking problem of nonnegative constant reference signals for unknown stable MIMO positive LTI systems with nonnegative constant disturbances. Our results exploit the structure of tuning regulators and show that any unknown stable MIMO positive LTI system can track any nonnegative constant reference signal while maintaining almost state nonnegativity.

The servomechanism problem for unknown SISO positive LTI systems via tuning regulators and clamping
In this paper we consider the servomechanism problem for SISO positive LTI systems. In particular, we solve the robust servomechanism problem of nonnegative constant reference signals for stable SISO positive unknown LTI systems with constant nonnegative unmeasurable disturbances under strictly nonnegative control inputs, using a clamping tuning regulator.

This paper fully discusses how to design an observer based decentralized fuzzy adaptive controller for a class of large scale multivariable non-canonical nonlinear systems with unknown functions of subsystems’ states. On-line tuning mechanisms to adjust both the parameters of the direct adaptive controller and observer that guarantee the ultimately boundedness of both the tracking error and tha...
متن کاملAdaptive Neural Network Method for Consensus Tracking of High-Order Mimo Nonlinear Multi-Agent Systems
This paper is concerned with the consensus tracking problem of high order MIMO nonlinear multi-agent systems. The agents must follow a leader node in presence of unknown dynamics and uncertain external disturbances. The communication network topology of agents is assumed to be a fixed undirected graph. A distributed adaptive control method is proposed to solve the consensus problem utilizing re...
متن کاملPerformance and robustness preservation in MIMO systems when applying SPR Substitutions
We are concerned in this paper by controlled Linear Time-Invariant (LTI) Multi Input Multi Output (MIMO) systems in continuous-time. We study here the preservation under strictly positive real substitutions (of zero relative degree) of coprime factorizations as well as stabilizing properties in parametrized controllers. We also tackle here both the preservation of well-posedness (of the trackin...
متن کاملFeedback-Based Iterative Learning Control for MIMO LTI Systems
This paper proposes a necessary and sufficient condition of convergence in the 2 L norm sense for a feedback-based iterative learning control (ILC) system including a multi-input multi-output (MIMO) linear time-invariant (LTI) plant. It is shown that the convergence conditions for a nominal plant and an uncertain plant are equal to the nominal performance condition and the robust performance co...
