Torque distribution based on central differential mechanism control for lateral handling stability [Yanal yol tutuş kararliliǧi için merkezi diferansiyel kontrolü tabanli çekiş torku daǧitimi]

A control algorithm has been proposed for multimodel switching control (mmsc) of the central differential mechanism of road vehicles. in such problems,the peformance parameters related to vehicle handling are expected to converge to reference values in the shortest possible time by the use of appropriate controllers. in the present approach,operating points of the system are determined at two different levels of the road friction coefficient and linear system models are obtained around these points. for each of the models,state feedback controllers,which are robust against the change of vehicle speed,are designed by solving linear matrix inequalities (lmi) feasibility problems. it is proved that the proposed algorithm satisfies stability and performance conditions during switching between the system models that are operative under varying road conditions. yaw rate reference tracking is achieved,driving stability ensured,settling time improved and oscillations in yaw rate and sideslip angle are reduced for the controlled vehicle.
