Robust Saturated Control Based Static Output Feedback for Steering Control of the Autonomous Vehicle via Non Quadratic Lyapunov Function

This chapter presents a robust nonlinear $$ H_\infty $$ Static Output Feedback control (SOF) design for steering control of the autonomous vehicle under actuator saturation, external disturbances, and taking into account the unavailability of the sideslip angle. The Takagi-Sugeno (T-S) approach is used to model both the lateral and lane keeping dynamics of autonomous vehicles. Based on the non-quadratic Lyapunov approach, a static output Feedback controller based on non-compensation parallel distributed technic the $$ H_\infty $$ stabilization conditions without saturation are developed. Then, a polytopic representation of the actuator saturation is investigated to express the robust non-qudratiquc stabilisation conditions of Vehicle lateral dynamic control with input constraints in term of LMIs. Finally, the simulation results show that the proposed controllers can stabilize the closed-loop system and present great lane-keeping and external disturbance rejection performances.
