Mathematical design and analysis of anti-lock brake system for electric vehicle based on brake-by-wire technology

摘要

The current study presents the derivation of mathematical modelling of anti-lock brake system solely from brake-by-wire perspective. The study also proposes permanent magnet DC (PMDC) motor to perform suitable braking action which is selected based on predetermined electric actuator characteristics. The brake system and electric motor specifications are then designed, taking into consideration maximum magnitude of electric vehicle power supply. In addition to that, a study case based on proportional integral derivative (PID) controller is carried out to further examine performance behaviour of the proposed mathematical model and the validity of computational specifications for brake system design as well as the PMDC motor. Simulation analysis and investigation which are conducted in MATLAB software revealed efficient operating brake system that leads to obtain desired control signal successfully with outstanding performance. Furthermore, the result output behaviour of the plant mimics predetermined brake system analysis which ensures the validity of the proposed mathematical design.
