Mathematical models and structures of the vehicle lateral stability stabilization system

Currently, intensive research is being carried out to improve the operational characteristics of car: vibration protection, smoothness, stability, controllability. These properties are largely determined by vehicle suspension, which provides a connection between carrier system and wheels vehicle. Significant attention paid development active suspensions, in additional actuators used form necessary characteristics, particular, linear DC motors. The use allows you control position car body, including its lateral roll. In article, relations obtained that establish dependence elastic deformations suspension car's roll angle on centrifugal force stationary mode. When developing linearized mathematical model object for study non-stationary modes, two-mass design scheme was operator equations were take into account elastic-dissipative sprung unsprung parts car, as well an action created actuator. It shown dynamic studied can be approximately described transfer functions second-order aperiodic link or oscillatory link. For first case, single-loop developed, closed terms heel with PID controller. second situation, it advisable two-loop internal flexible feedback loop deformation external using possibility forming signal strain rate wind circuit help EMF sensor motor shown.
 On basis block diagram, computer typical parameters object, made transient processes working off disturbance change force. Based simulation results, found developed ACS high accuracy stabilizing angle.
