Modelling and Control of Four-Wheel Anti-Lock Braking System

Minimal stopping distance, guaranteed steering ability and stability are the three most important purposes in anti-lockbraking system (abs) realm. the abs system is a nonlinear, time variant and multivariable system with someuncertainties. some research work has been carried out on abs control systems using intricate methods, which areexpensive to implement. in this paper at the first step, the system interference is decreased via decoupling matrix andthe abs is controlled with a robust diagonal controller. in fact, a decentralized control technique is used for our abscontrol mechanism. at the second step, we exploit a multivariable technique in linear control to attack the problem.this is the designed linear control with multivariable technique. the optimal eigenstructure assignment with thegenetic algorithm (ga) method is also applied. simulation and comparison studies are used to show the effectivenessof the proposed methods.
