Abstract: In the process of reconstruction
for the existing measure and control system,academic design of chassis
dynamometer control system under simple transient condition is made depending
on the GB18285 \ 2005 regulation.Hardware design and corresponding control
strategy of human-computer control system are analyzed and a proposal based on
automatic driving system is put forward.Certain hardware electro-circuit is
utilized to make the torque adjust fast.Electronic simulation technology is
adopted to simulate the resistance force and inertia of the vehicle.Moment load
for the chassis dynamometer is achieved by comprehensive application of
theories of predictive control,fuzzy control and decoupling control.Theoretical
analysis and testing results indicate that the system obtains a satisfying
response time and the chassis dynamometer can be controlled according to the
dynamometer load which is automatically set.
