This book presents high-quality original contributions on positive systems including those
with positivity in compartmental switched systems Markovian jump systems Boolean networks
interval observer design fault detection and delay systems. It comprises a selection of the
best papers from POSTA 2018 the 6th International Conference on Positive Systems which was
held in Hangzhou China in August 2018. The POSTA conference series represents a targeted
response to the growing need for research that reports on and critically discusses a wide range
of topics concerning the theory and applications of positive systems. The book offers valuable
insights for researchers in applied mathematics control theory and their applications.
