Abstract

In this paper, a synthesis method of a reconfigurable fault-tolerant control system for a steer-by-wire vehicle is proposed. The proposed control law consists of a linear feedback control law and a control allocator based on online optimization. It is shown that the input-output property of the control allocator can be regarded as a sector bounded nonlinearity. Based on this fact, a design method of a controller that guarantees stability of the overall system is proposed. The effectiveness of the method is shown through numerical examples.
