The 16th IFAC Workshop on Time Delay Systems (TDS 2021), which continues the long-time successes of the workshop series since 1998 and seeks to meet the growing interest of the international scientific community in systems with time delays, will be held in Guangzhou, China on September 29-October 1, 2021. The TDS 2021 technical program will include contributed and invited papers, as well as tutorial sessions and workshops, focusing on theoretical advances and technological applications of systems and control related to time delay systems. This focus includes but is not limited to modelling and identification, analysis, filtering and estimation, stability and stabilization, safety, structural properties, robustness, approximation techniques and numerical methods, data-driven and machine-learning methods, control schemes and application in process control, vibration control, networked systems, autonomous agents, communications, bio-engineering, economics and other fields. Particularly welcomed is the latest progress in emerging problem areas such as cyber-physical systems, cloud-based control, and in emerging applications such as smart grid, biomedical systems, intelligent transportation, intelligent manufacturing and automation.

Situated at the heart of the thriving Pearl River Delta and in close proximity to Hong Kong and Macao, Guangzhou is the third largest city in the Mainland China that boasts a unique southern China culture blended with its fast-developing modern metropolitan ambience. The city, readily accessible from the world’s major airports, is known for many of its attractions and promises to offer most unforgettable cultural, sightseeing, dinning, and entertainment experiences.

TDS 2021 recognizes excellent student contributions by presenting a Best Student Paper Award for a paper whose primary author and presenter is a student.
