Abstract

This paper presents an application of H robust control theory to a Front-Wheel-Steering (FWS) mechanical model (complex model) substituted for the linearized dynamics model. The input signal of the structure can be determined by a given steering angle, and then a Linear Matrix Inequality (LMI) based on H method is proposed to solve the uncertainty problem under the conditions of the mass and velocity. Finally the simulation results show that the remainder velocities and masses are located inside the assignment boundary.
