Abstract :
In this paper, the control theory of PWA (Piecewise Affine) systems is applied to vehicle ABS (Anti-lock Brake System) controller design. By approximating the slip-related nonlinear characteristics using PWA function, and considering the vehicle speed as the slow time-varying parameter which is unknown in future, but measurable at current sampling time, the vehicle braking model is treated as PWA system with measurable time-varying parameter. Then a parameter-dependent ABS controller is designed according to the control theory of discrete-time piecewise affine systems. At last, the effectiveness of the ABS controller is assessed on a detailed full-car simulator (veDYNA, tuned to fit the characteristics of Red-flag Mingshi CA7180A3E).
