A Necessary and Sufficient Condition for High-Frequency Robustness of Non-Strictly-Proper Feedback Systems
We consider stability and robustness of feedback systems, where plant and compensator need not be strictly proper. In an earlier paper [1] we described a functional R∞ which, when negative, guarantees closed-loop instability as a result of parasitic interactions in the feedback loop. In our main result, Theorem 5, we prove that, when R∞ > 0, there exist perturbations of plant and compensator fr...
متن کاملA geometric perspective on H2-optimal rejection by measurement feedback in strictly-proper systems: The continuous-time case
In this work, we develop a geometric method for solving the problem of H2-optimal rejection of disturbance inputs in continuous-time linear systems without feedthrough terms from the control input and the disturbance input to the controlled output and the measured output. A necessary and sufficient condition for the solvability of the problem is expressed in terms of a pair of subspaces, a cont...
متن کاملA numerical method for the computation of proper denominator assigning compensators for strictly proper plants
Given a right coprime MFD of a strictly proper plant P (s) = NR (s)DR (s) −1 with DR (s) column proper a simple numerical algorithm is derived for the computation of of all polynomial solutions [XL (s) , YL (s)] of the polynomial matrix Diophantine equation XL (s)DR (s) + YL (s)NR (s) = DC (s) which give rise to the class Φ (P, DC) of proper compensators C (s) := XL (s) −1 YL (s) that when empl...
متن کاملAdaptive Consensus Control for a Class of Non-affine MIMO Strict-Feedback Multi-Agent Systems with Time Delay
In this paper, the design of a distributed adaptive controller for a class of unknown non-affine MIMO strict-feedback multi agent systems with time delay has been performed under a directed graph. The controller design is based on dynamic surface control method. In the design process, radial basis function neural networks (RBFNNs) were employed to approximate the unknown nonlinear functions. S...
متن کاملEigenstructure Assignment for Semi-proper Systems: Pseudo-state Feedback
The general problem of assigning the eigenstructure of semi-proper systems, using state feedback, is first considered. Standard eigenstructure assignment algorithms invariably assume the direct transmission matrix to be null. Consequently, they are suitable only for strictly proper systems. Algorithms do exist for assigning the eigenstructure of semi-proper systems, but they suffer from a lack ...
