Slide Mode Control for Integrated Electric Parking Brake System

Abstract EN

The emerging integrated electric parking brake (IEPB) system is introduced and studied.

Through analyzing the various working stages, the stages switched IEPB system models are given with the consideration of the friction and system idle inertia.

The sliding mode control (SMC) method is adopted to control the clamping force by the widely used motor angle and clamping force relationship method.

Based on the characteristics of the state equations, two sliding surfaces are built to control the motor angle and current, respectively.

And in every working stage, the control stability is guaranteed by choosing the control parameters based on Lyapunov theory and SMC reachability.

The effectiveness of the proposed control system has been validated in Matlab/Simulink.
