KOFMAN, E.. Discrete event control of time-varying plants. Lat. Am. appl. res. [online]. 2005, vol.35, n.2, pp.135-141. ISSN 0327-0793.

This paper studies the use of Quantized State Control (QSC) in Time-Varying (TV) plants. Making use of a Lyapunov analysis, the stability properties of Time Invariant QSC are extended to the non- stationary case. Then, based on the resulting stability theorem, a design algorithm is developed. Finally, the use of this algorithm -which allows the design of QSC controllers according to stability and convergence speed features- is shown with the design and the simulation of an illustrative example.
