Nonlinear LQG Slip Controller Based on an Empirical Model for a Three Wheel Hybrid Vehicle

A three wheels recreational vehicle propelled by its unique rear wheel is studied for the purpose of regenerative braking control. To ensure the stability of the vehicle and the safety of the pilot, the slip ratio of the powered wheel must be limited during regenerative braking. In this study, a design of a LQG slip tracking algorithm is proposed. The non-linear model is based on experimental tests and the controller has been validated by simulations and road tests.
