Control System Modeling for Automotive Brake Test-Bench Based on Discrete Closed-loop and Phase-locked Loop
According to the law of rigid body around fixed axis rotation,established the mathematical model of motor drive current and instantaneous rotational speed．From the ideal situation of the simulation，according to the same discrete intenrval of time equal to the same increment of spindle angular velocity conditions,established the discrete closedloop control system model．in allusion to the disadvantage of calculating corresponding braking current by the instantaneous speed and the instantaneous braking torque measured during the last interval,proposed the control method of calculating braking current by the instantaneous speed and the instantaneous braking torque measured all discrete intervals before current time．Discussed emphatically the computer controlled method based on the discrete closed-loop and phase-locked loop theory which call be used to design the braking current．Evaluated the advantages and disadvantages of the model, and proposed the improved direction．
