History of SSSC 

The origins of the meetings on Systems Structure and Control (SSC) under the technical sponsorship of IFAC go back to the IFAC workshops first held in Prague, Czech Republic in 1989 and 1992 and subsequently in Nantes, France in 1995 and 1998 as conferences. Also, in late 1997 a Conference on SSC, sponsored by IFAC, had been held in Bucharest, Romania. The meeting returned to Prague in 2001, as an IFAC symposium; its 2nd Edition was held in Oaxaca, Mexico, in 2004, the 3rd at Foz do Iguassu, Brazil in 2007, the 4th in Ancona, Italy in 2010, the 5th in Grenoble, France (2013), the 6th in Istanbul, Turkey (2016) and the 7th in Sinaia, Romania (2019).

History of TDS 

IFAC Workshop on Time Delay Systems brings together the scientific community in systems with time delay from theory to applications. Strong interest to this research area has culminated in a series of workshops, starting first in July 1998 (Grenoble, France) and followed by those in September 2000 (Ancona, Italy), December 2001 (Santa Fe, USA), September 2003 (Rocquencourt, France), September 2004 (Leuven, Belgium), July 2006 (L’Aquila, Italy), September 2007 (Nantes, France), September 2009 (Sinaia, Romania), June 2010 (Prague, Czech Republic), June 2012 (Boston, USA), February 2013 (Grenoble, France), June 2015 (Ann Arbor, USA), June 2016 (Istanbul, Turkey), June 2018 (Budapest, Hungary), September 2019 (Sinaia, Romania), September 2021 (Guangzhou, China). In this way the series of annual IFAC Workshops on Time Delay Systems has been established, and the present edition being the 17th of the series to be held in Montreal, Canada in September 2022.

History of LPVS 

Motivated by the active community in that topic, the first IFAC LPVS workshop was organized in Grenoble, France, in 2015. In 2018, the 2nd IFAC LPVS workshop was held jointly with the 9th IFAC Symposium on Robust Control Design (ROCOND), in Florianópolis, Brazil. In 2019, the workshop was organized in Eindhoven, the Netherlands. Last year, in 2021, the 4th IFAC LPVS was organized in Milano, Italy.
