Quantized Guaranteed Cost Control for Networked Control Systems With Random Delays and Interval Parameters

ABSTRACT This paper investigates the quantized guaranteed cost control design (GCCD) for networked control systems (NCSs) with interval parameters and random delays. A comprehensive NCS model is established, incorporating three key elements: Interval parameters represented as convex combinations of endpoints, random delays governed by a Markov chain, and quantization effects described by the sector‐bound method. Based on the model, sufficient conditions for the GCCD are derived using the Lyapunov functional approach combined with the cone complementary linearization (CCL) algorithm. Numerical simulations demonstrate the efficacy of the proposed method.
