Transfer matrices with positive coefficients of descriptor linear systems
Tadeusz Kaczorek, Łukasz Sajewski · Journal of Automation Electronics and Electrical Engineering · 2024
Transfer matrices with positive coefficients of descriptor positive linear continuous-time systems are addressed. Two methods of checking of the positivity of descriptor linear systems are proposed. It is shown that if the positive descriptor system is asymptotically stable then all coefficients of its transfer matrix are positive.
