Abstract

Abstract:

We present a bandwidth scheduling based network congestion control strategy to avoid the degradation of quality of performance (QoP) caused by the reduction of quality of service (QoS) in networked control system. We initially construct a congestion state and bandwidth based linear time invariant (LTI) model. We then control network congestion with linear quadratic regulation (LQR) and dynamic bandwidth allocation. Simulation results demonstrate its effectiveness.

Key words: linear quadratic regulation, networked control system, quality of service, dynamic bandwidth allocation
