Behaviour of control systems including controlled convertors, especially rectifiers : a review of existing theories
J. Lagasse,R. Prajoux +1 more
TL;DR: In this paper, the authors considered the different models and methods to be found in published works by separating them into three classes: linear continuous, discrete small signal, discrete large signal, and compared their respective uses and advantages, and gave the general results which they allowed to obtain.

A Simple Method for a Quick-Response Chopper PWM System with Small Steady-State Error
T. Mochizuki,Y. Tanaka,M. Hyodo +2 more
TL;DR: The dynamic behaviour of a chopper PWM system in a closed-loop is analized by using the models for small signal perturbation and a simple method is proposed to quick-response system with small steady-state error, using the dead-beat gain and the bias function.

Generalized pulse-modulated feedback systems: Norms, gains, Lipschitz constants, and stability
R. Skoog,G. Blankenship +1 more
TL;DR: In this article, sufficient conditions for the asymptotic stability of pulse-modulated feedback systems are developed from the operator theoretic viewpoint. But these conditions are restricted to the case that the feedback system is a Lipschitz continuous operator on the extended space L 1e.

A stability criterion for pulse-width-modulated feedback control systems
G. Murphy,S. Wu +1 more
TL;DR: Aizerman's method for investigating asymptotic stability in the large, which was extended by Kodama to encompass nonlinear sampled-data systems, is further extended in this article.

Ripple instability in closed-loop control systems with thyristor amplifiers
F. Fallside,A.R. Farmer +1 more
TL;DR: In this paper, a more accurate analysis of the sampling action of the amplifier in the presence of alternating component voltages in the loop was made, taking into account the effect of the output ripple voltage.
Journal ArticleDOI
Stability study of controlled rectifiers using a new discrete model
TL;DR: In this paper, a small-signal model for a convertor is developed which takes into account the discrete behaviour of the controlled rectifier and allows the use of standard sampled-data control-system theory in the stability analysis of the system.
Journal ArticleDOI
On the stability of pulse-width-modulated feedback systems
TL;DR: It is shown that the result in 2) implies that the criterion in 1) essentially becomes the well-known Nyquist criterion for sample-data systems when the pulse-width-modulator frequency is sufficiently large.
