Comments on "Model reduction using the Routh stability criterion"
A model reduction technique suggested in the above paper is discussed. Although the proposed method is very simple and devoid of any tedious calculations it is shown that the applicability, of the technique is restricted. ...
On the Lyapunov design of systems with zeros in the right-half plane
The effect of a zero in the right-half plane on the controller derived through the stability theorem of Lyapunov is considered through a simple illustrative example. It is shown that the controller should have the form of ...
Multiple constraints in optimal control problems
The origin of multiple constraints on a control function in both lumped and distributed systems is investigated. Equivalence and comparability notions are discussed. It is pointed out that multiple constraints have a special ...
An active feedback block and its applications
The active feedback block considered in this correspondence consists of three identical single-pole amplifiers and a resistive network, and has a positive slope in the gain frequency characteristics over a certain frequency ...
On maximally flat sharp cutoff low-pass filters
Maximally flat (MF) low-pass filters with multiple pairs of coincident or distinct imaginary axis zeros are investigated and compared with the all pole Butterworth filters. It is shown that for the same ordern, finite zero ...
On simplification of unstable systems using Routh approximation technique
A modified modeling procedure using the direct Routh approximation method (DRAM) for a class of unstable systems has been presented in this technical note. The proposed method yields a model which is based on an improved ...
Design of IIR filters using Pseudo-Boolean methods
Pseudo-Boolean methods are particularly suited to problems in which the variables take only two values, 0 and 1. In this paper, a method is presented for solving nonlinear pseudo-Boolean inequalities, and is applied to ...
Derivation of an optimal estimator for distributed parameter systems via maximum principle
The problem of estimation for a class of distributed parameter systems is approached via maximum principle. As a consequence, the advantages of the "optimal control" point of view for tackling the estimation problem for ...
