Abstract

This paper studies H control for networked control systems with packet loss. In networked control systems, packet loss is one of major weakness because the control performance deteriorates due to packet loss. H control, which is one of robust control, can design a controller to reduce the influence of disturbances acting on the controlled object. This paper proposes an H control design that considers packet loss as a disturbance. Numerical examples show that the proposed H control design can more effectively reduce control performance deterioration due to packet loss than the conventional H control design. In addition, this paper provides control performance comparisons of H control and Linear Quadratic (LQ) control. Numerical examples show that the control performance of the proposed H control design is better than that of the LQ control design.
