A stochastic controller for anti-skidding microprocessor system

The paper deals with the analysis of an original anti-skid controller suitable for an electrical traction drive when the qualification of automatic steering imposes strict rules about the time running, target braking and vehicle stability and handling. The presented controller includes anti-skid braking and anti-spin acceleration functions. After an analytical discussion about mathematical modelling and identification of wheel-road conditions by means of an original stochastic modellisation, a stochastic input controller schema is proposed. The main feature of such a controller is the overcoming of a deterministic point of view of standard anti-slip systems. Furthermore the control strategy is also oriented to a maximisation of traction effort in no-adherence conditions
