Systems Having Clegg Integrators
- AUTHORS: Hu., H., Zheng, Y., Chait, Y., and Hollot, C.V.
- ABSTRACT: In this paper, we consider control systems utilizing so-called
Clegg integrators. A Clegg integrator is a linear integrator with reset
mechanism whose describing function $\frac{1.62}{\omega} \angle{-38.1^{\circ}}$
has magnitude slope equivalent to that of a linear integrator, but with
$51$ less degrees of phase lag. The potential advantages of using Clegg
integrators to meet stringent design specifications has been demonstrated
in the literature, however, stability analyses are missing. This paper
addresses the zero-input stability of such control systems and provides
a definitive stability condition for second-order plants as well as
a providing preliminary results for higher-order plants.
- STATUS: to be presented at the 1997 American Control Conference.
