The Role of Models in Self-adaptive and Self-healing Systems [PDF]

, 2009
Self-healing and self-adaptive systems dynamically react on changes in the environment. They enable software systems to adjust to new conditions and work optimally even in unstable environments.

Incremental networked predictive control of multi‐agent systems with plant‐model mismatch and random communication constraints

IET Control Theory & Applications, 2022
In this paper, we discuss the cooperative output tracking problem for networked multi‐agent systems (NMASs) with plant‐model mismatch as well as random communication constraints in the forward and feedback channels of each agent.

Communication constrained robust guidance strategy using quantized artificial time delay based control with input saturation

IET Control Theory & Applications, 2021
This work proposes the use of a logarithmic quantizer to minimize the computational load on the onboard processor of missiles. The quantizer output discretizes the continuous guidance command to a finite set of predefined discrete levels.
