The SIAM Activity Group on Control and Systems Theory Best SICON Paper Prize (SIAG/CST Best SICON Paper Prize) is awarded every two years to the authors of the two most outstanding papers, as determined by the prize committee, published in SICON in the three calendar years preceding the award year.

A candidate paper must make significant research contributions to the field of control and systems theory and must have been published in SICON in one of the three calendar years preceding the year of the award.

For the 2025 award, the paper must have been published between the dates of January 1, 2022 - December 31, 2024.- Nominator’s letter of recommendation for candidate paper
- Bibliographic citation for candidate paper
- Digital version of the candidate paper (PDF required)

Two SIAG/CST Best SICON Paper Prizes will be awarded each prize cycle and includes a plaque. If the selected paper has multiple authors, each author will receive a plaque. At least one recipient for each prize paper is invited to attend the award ceremony and present the paper as a short plenary lecture at the meeting. SIAM will reimburse the recipient for reasonable travel expenses incurred in attending the award ceremony and giving the lecture.

The prize will next be awarded at the 2025 SIAM Conference on Control and Its Applications.

The Chair of the SIAM Activity Group on Control and Systems Theory will announce the awards at the meeting and present the awards to the recipient(s). At least one author of each paper is encouraged to attend. The announcement of the award will appear in *SIAM News*.
