The paper provides extended methods for control linear positive discrete-time systems that are subject to parameter uncertainties, reflecting structural system constraints and properties when solving the problem of quadratic stability. By using an extension Lyapunov approach, stability is presented become apparent in pre-existing positivity design feedback control. approach prefers representati...

This paper considers the fixed-time control problem of a multi-agent system composed class Euler–Lagrange dynamics with parametric uncertainty and dynamic leader under directed communication network. A distributed observer is first proposed to estimate desired trajectory then robust controller constructed by transforming uncertain systems into second-order utilizing backstepping design procedur...
