This thesis is the research for the special properties of anti-
lock braking system and propose the design named anti-lock
braking fuzzy controller. Also design another testing platform
of anti-lock braking in order to practice the designd controller
and make necessary verification and execute the laboratory
research of anti-lock braking system. According to the
development of theory, we have inferred the mathematicmodels
based on the dynamic propert y of braking which include
vehicledynamic tire force model and hydraulic system dynamics.
Then figures theseout by fuzzy controlling principle and control
the solenoid valve of hydraulic braking system through fuzzy
inference which may keep the braketorque around the best value
and achieve the demand of minimum brakingdistance and best
operating control. Through simulink in matlab software,the block
diagramof anti-lock braking system is constructed and
thecomputerized imitation of anti-lock braking system has
provided technicalreference to design the fuzzy controller by
real parameters by hard wareequipment. For the development
on testing platform, in order to test and understandthe
motivated efficiency of anti-lock barking controller, this
testingplatform has been designed according to the theory
experience and enableus to obtain all laboratory figures and
cross-testify them. We may have complete understanding on the
operation of anti-lock brakingsystem and judge the situation of
controller to make improvement orrectification. It is certified
that this fuzzy controller has achievedits efficiency by
laboratory result.
