tilt strategy. Two multi-objective Genetic Algorithm tuning methods (MOGA and NSGAII) were employed to optimise both the fuzzy
output membership functions and the controller parameters. The objective functions incorporated the tilt response and roll gyroscope
signals for the deterministic (curved track) profile, and lateral acceleration for the stochastic (straight track) profile. Simulation results
discuss the effectiveness of using the presented techniques for tuning the fuzzy control scheme via multiple objectives. The proposed
scheme is compared with the conventional nulling-tilt approach and a manually-tuned fuzzy controller.
