The invention discloses a
hybrid electric vehicle belt-driven started generator (BSG)
torque ripple compensating controller and a construction method of the
hybrid electric vehicle BSG
torque ripple compensating controller. The
torque ripple compensating controller controls a composite controlled object. The torque
ripple compensating controller comprises a PI adjuster, an extended
inverter control module and a current compensating module. The composite controlled object comprises a
hybrid electric vehicle BSG, a photoelectrical coded disk and a revolving speed and electrical degree calculation module. A neural network is adopted to build the current compensating module, the neural network is of a four-layer structure, and the neural network is trained by the adoption of the Powell
algorithm. According to the hybrid electric vehicle BSG torque
ripple compensating controller and the construction method of the hybrid electric vehicle BSG torque
ripple compensating controller, the current compensating module is recognized through the neural network, the current
harmonic wave of a BSG motor can be restrained effectively, and the torque ripple of the motor is reduced significantly, so that the hybrid electric vehicle BSG
system has good dynamic and static characteristics and very strong robustness.
